  1. That is correct.

  2.  @wronguniverse_2930  Not usually. Occasionally, some websites (like email or other secure pages) may want extra verification when you try to log in, because you have a different public IP, but its not too common.

  3.  @harismith497  The exact steps depend on your router. In general, there should be a section that let's you change the network-specific settings, including the router's IP address. You can change it to whatever you want, as long as you understand subnets. For your individual devices, that depends again on your router and devices. Most devices should have a network setting that let's you request a new IP address from the router. It may give it the same one or a different one.

  4.  @J_Klutch  ok there tough guy. lmao.

  5. Those are private IP address ranges meaning they can only be used inside of a network. You can have multiple networks with the same IP address since they don't talk to each other. There are public IP addresses which are used on the internet. And no, not all networks start like 192.168.x.x. Look up IP classes A,B, & C.
    2
  6. You use a different subnet that has more IPs available.
    2
  7. Larger subnet.
    2
  8. Just depends on how your router's DHCP server is configured. Its not really that big of a deal. You can likely change it if you want in the router settings.
    2
  9. The actual answer is 254. However, your router needs an IP address so 1 of them has to be reserved for it.
    2
  10. You will need to create a different subnet for your 2nd router. This involves changing the subnet mask. I suggest watching some videos on subnet makes and how to perform subnetting to get a better idea.
    2
  11. Not sure what you're trying to ask.
    2
  12. You won't have enough IP addresses so any devices past 253 won't get an IP address. You'll need to use a larger IP space.
    2
  13. It doesn't matter if you leak it or not. That's a private IP address. Its completely useless to anyone outside of your home network.
    2
  14. Has nothing to do with an ethernet cable or where you live. Your router is just configured to work on the 192.168.2.xxx network space. Nothing necessarily special about that.
    2
  15. Don't know the exact steps, but it should be in the console's network settings.
    2
  16. Depends on your router and how it is configured to assign IP addresses. It doesn't really make a difference.
    2
  17. Is your device connected via Wifi? If so, it has an IP address, otherwise it wouldn't be able to talk to the network. If its on ethernet, its ethernet adapter will have an IP address, but the wifi adapter may not have an address until it connects via wifi.

  18.  @Eternal_Tech  Ah. I see. I never watched her show so I didn't know that part. I just knew that she had a TV show, but that's it. Thanks for the info.
    2
  19. Which IP are you talking about? public (assigned by your internet provider) or private (inside your network)?
    2
  20. What do you mean you don't have a router? If you don't have one, you wouldn't be able to go online.
    1
  21.  @kiiturii  You always need a router somewhere. That's the job of a router: to route IP packets. It is extremely unusual to not have a router at home, but if you don't your ISP would act as the router. Those ethernet ports you have, where do they lead to? The cable behind the plug has to lead somewhere.
    1
  22.  @kiiturii  What's the brand and model number of that switch? Its an unusual setup you have.
    1
  23. The hotspot device acts as a router in that case. The hotspot will have a DHCP server built-in which will give the devices that connect to it IP addresses.
    1
  24. Open a Terminal window and type in: ifconfig I believe you can also see your computer's IP address in Network Settings. I don't remember the exact steps, but it should be too hard to find.
    1
  25. Only your ISP can change your public IP address. I don't understand how you need to change your IP address for work....
    1
  26. lmao. Why are you here then? If technology is ruining us, why are you trying to learn about IP addresses? Doesn't make any sense...
    1
  27. Routers have 2 IP addresses. 1 public IPv4 address. This is unique and is assigned by your ISP. There's a private IP address. This address is only used internally in the network.
    1
  28. It looks like it depends on the individual hosts. Some hosts don't respond to pings. You may want to type in this question into google to get a more accurate answer.
    1
  29. That's an ambiguous question.......
    1
  30. I don't understand your question...
    1
  31.  @marekbank3996  There is a website called What is my IP. Go to it and it will tell you your public facing IPv4 and IPv6 addresses.
    1
  32. What??
    1
  33. What do you mean by that?
    1
  34. You would need to use a VPN service.
    1
  35. You can use a VPN connection, but you still have your same IP from your provider. Its just that it gets 'masked' behind the VPN's server's IP address. Other than that, there's no other feasible way to get another public IP. If you have a business internet account, you may be able to purchase a block of IPs, but that depends on your provider.
    1
  36. It doesn't matter. Some routers/ISPs use different IP ranges for reasons don't know why. In the end, as long as you know what ports you need to forward and to what IP addresses, that's all that matters.
    1
  37.  @PekmezV2  IPconfig will show you the list of network adapters on your PC as well as their network config. Look for the network adapter you want. If its wifi, for instance, it should say something like "Wireless LAN adapters Wi-Fi" or similar. That should be the IP address of your network adapter. Make sure you type it in correctly on your router's port forward settings.
    1
  38.  @PekmezV2  I'm not really sure. Most likely is a weird issue on your router side.

  39. The modem more or less acts as a bridge between your network and your ISP's network. It connects via phone line (DSL), coax (cable internet), or fiber (fiber internet).
    1
  40. Yes. The router is still a host device in the network so it needs its own IP address.
    1
  41. If they're on the same network, neither device will work correctly. I know on Windows you get a network notification telling you there's an IP address conflict. I don't know what other devices do in terms of notifying you.
    1
  42. Yep. In most home networks, the router handles DHCP, DNS, and a few other services. In reality, the router just forwards DNS queries to your ISP's DNS servers. The internal DNS server is only used for devices inside of your network.
    1
  43. The devices have different private IP address, but will share the same public IP address. That's because in order to go online, each device needs a public IPv4 address. We don't have enough for all devices in existence, so most ISPs use something called NAT. This essentially allows your router to share a single public IP address with all the devices in its internal network.
    1
  44. The same public IP or private IP?
    1
  45. That's an IPv6 address.
    1
  46. That's just how your router is configured. Different manufacturers sometimes use different IP address ranges.
    1
  47. Of course. These are private IP addresses. They're only used inside of his network and completely useless to anyone outside of his network.
    1
  48. What's the exact minute and second in the video you're referring to?
    1
  49. ISPs sometimes use different IP spaces for their home routers.
    1
  50. Cyber what? That doesn't make sense.
    1
  51. That's why I use Sponsorblock. It automatically skips over sponsored segments.
    1
  52.  @manikbaba9410  Look up VLSM (variable length subnet mask). Its a different approach to subnetting.
    1
  53. Yep.
    1
  54. From what I've read, you need to understand how to do subnets, but it isn't a big part of the exam. I strongly suggest using other resources for studying for the CCNA. NWC is a good presenter, but he lacks depth. His "CCNA" video series is far from complete and it doesn't even go into actual CCNA content. Its mostly general networking, which is good to know, but you need a lot more information.
    1
  55. To an extent, yes. Its not like in the movies where you can figure out someone's exact location. IP address lookup pages can give you some geographic information, such as country, state, and city/town. However, it does not provide information like names, street addresses, etc. Sometimes, these lookup pages can be inaccurate so the information you find may not be accurate.
    1
  56. I agree but that's his teaching style.

  57. As far as I'm aware, even if you're connected to a wifi network, your phone still has a connection to the cell tower and has an IP address from AT&T.
    1
  58. These are private IP addresses. They are only used inside of your network. So even though many home networks use the 192.168.1.0/24 subnet mask, it doesn't affect my home network or yours. These IP addresses are not routable. That means they are not used on the internet. In larger networks like in the business and enterprise, you use larger subnets to accommodate more host devices. You can also usually use larger subnets on home routers, but it doesn't really make sense. It is unlikely you will have more than 253 devices on your network at the same time.
    1
  59. You'll need a larger subnet.
    1
  60. Its out of the scope of this video. But there's a protocol called DHCP - Dynamic Host Configuration Protocol. Its a protocol that automatically assigns network devices IP addresses. You need a DHCP server for this. In most home networks and small business networks, the router contains the DHCP server. However, in larger and more complex networks like medium and large businesses and enterprise networks, the DHCP server is usually separate to the router. And you may have multiple DHCP servers for different networks and/or for fail over. In short, there are 4 steps for a device to get an IP address - DORA DHCP Discover - The device (say laptop) is trying to discover what DHCP servers are out there in the new network it just connected to DHCP Offer - The DHCP server offers the laptop an IP address DHCP Request - The laptop requests that IP address from the DHCP server DHCP Acknowledge - The laptop and DHCP server acknowledge the information and the laptop know has an IP address

  61. You use a larger subnet.
    1
  62. To an extent, yes. But its not like the movies where you can figure out a person's address. There are IP lookup websites where you can enter an IP address and it will give you information such as what internet provider its from, and approximate location like country, state, city, town, etc. It may not be entirely accurate, though.
    1
  63. If you're not connected to any network, then you won't have any IP address on your device.
    1
  64. That's normal.
    1
  65. Just the way the router is setup. I know Comcast routers use that 10.x.x.x IP network.
    1
  66. The default gateway is a client device and requires its own IP. You don't absolutely need a default gateway if none of your computers will need to talk to another network.
    1
  67. That's just how networks work. The first IP is the network ID. It identifies the network. The last address is the broadcast address. It is used to send broadcasts to all devices on that subnet.
    1
  68. That would be your public IP address. If your internet provider has IPv6 enabled, you will probably see a very long string of letters and numbers.
    1
  69. You would use a larger subnet.
    1
  70. You will have a new IP address from your new cell provider. Your home internet IP will still be the same.
    1
  71. Its to identify that IP network.

  72. Lol no. Oprah is a TV celebrity who had a TV talk show. I'm not entirely sure what its about, but he just use her as an example to make the video a bit more engaging.

  73. Can you ping your ESXi host from your PC?
    1
  74.  @TheSympathon  You'll have to make sure that whatever ESXi version you are trying to install supports your tower's hardware, mainly the CPU and network adapter. Since ESXi is enterprise software, they have a list of supported hardware for the respective ESXi version. I found that out several years ago. I tried to repurpose my old gaming PC as an ESXi host. The motherboard uses a Realtek NIC which VMware does not support. I had to run some patches/mods to get it to work with that NIC.

  75. Are both of you on the same internet connection? if so and if the block is an IP block, it will prevent you from playing the game.

  76. ??????????

  77. Gonna need a lot more information than that.....
