  2. It may be that your router or ISP is blocking ping requests on your public IP address.

  3. They may have static IP addresses available, but probably not for residential customers. If you upgrade to a business account, you may be able to purchase a static IP or block of them from your provider. I don't believe there are any technical reasons as to why they can't do it for residential customers, but since the vast majority of home users have no need for static IP addresses, there's really no incentive for providers to sell them.

  4. That's why IPv6 was created.

  5. Your comment, as written, is also misleading. You meant public IP address. Yes, only your router has a public IP address. All of your devices connected to your router have a private IP address, otherwise, they wouldn't be able to talk to your network.

  6. Go to his channel and look for the CCNA series playlist. Just note that there's still a ton of information missing. Its not a complete CCNA course as his video titles imply.

  7. Your computer just tries to ping it. Doesn't mean it will be successful though. A lot of routers have firewall settings in place preventing it responding to ping requests so your PC may not get any response.

  8. Yep

  9. Look up NAT. There are 2 main kinds of IPv4 addresses: Private and public. Private IP addresses are only used inside of your network. Public IP addresses are routable, that means they can be used on the internet. Your ISP assigns your router a single public IP address. Routers have something called NAT (Network Address Translation) that allows multiple devices inside of your home network to talk to the internet with a single public IP address. That's more or less the gist of it.

  10. I suppose in theory you could do that. In reality, its not going to work. All current network devices are designed to work with either IPv4 and IPv6. If you create your own standard, it won't work with any current devices unless they are updated to support your new standard which is not going to happen. Things would need to be re-designed in order to support a new standard. And what about devices/software that are obsolete or from manufacturers that don't exist anymore?

  11. Can you explain?

  12. Nope. Its most likely some other technical problem: maybe wifi router, modem, home wiring, or ISP's wiring.

  13. You could, but you then have the problem that ALL devices would need to be updated. Network devices are programmed for IPv4/6. If you make your own protocol, how are you going to get all manufacturers on-board? What about devices that are discontinued or from companies that don't exist anymore?

  14. If you're not computer literate, you're not the target audience. not trying to be rude, but this is part of a CCNA training series which deals with enterprise networking. Its already assumed/expected that you have some working knowledge of computers prior to trying to learn this. I strongly suggest you watch some basic computer/IT training videos and familiarize yourself with computers and IT concepts before coming back here.

  15.  @Hectorreigns_  lol oooo please what??

  16. In theory you could do that, but the problem is who is going to decide that? How are you going to get ALL companies/parties involved to agree on it? This is a massive undertaking that will require almost re-engineering a lot of things and retrofitting things that were never designed to work in that way. How are you going to support devices that are obsolete or from companies that don't exist anymore? This problem was pretty much solved with IPv6 which has a much larger IP space than IPv4.

  17. It would be extremely unlikely. His videos are decent, but he still lacks a lot of information that is on the exam. And I do mean a lot. He hasn't even shown you how to configure a Cisco router or a switch.

  18.  @allinzaya7057  Jeremy's IT Lab has good CCNA videos. He May not be as energetic as Network Chuck, but his series is complete.

  19. Everything would need to be updated in order to support a new IP standard. This would be impractical because there are many companies that no longer exist and/or don't provide updates to certain devices or software versions.

  20. Imagine it happens in the middle of a flush...

  21. In reality, we don't use Class addresses anymore. You can use CIDR (Classless Inter Domain Routing) to breakup an IP network into smaller or larger sub networks (subnets).

  22.  @月見かしゆき  Sorry but that doesn't make sense. Even old computers can have IP addresses if they're connected to a network. If we're talking very old operating systems, say pre Windows 95 and similar, they may not support TCP/IP or have built-in support for it.

  23. You're free to use any valid IPv4 address you want (except for reserved addresses like loopback, broadcast, and network ID). Its just that you have to understand how IP addresses work to make sense of why we use certain IP blocks for certain things. IPv4 has technically been exhausted for several years, but the internet still works.

  24. lol no. You can't sell it since your ISP owns it, not you.
