Join Mike Meyers for an in-depth discussion in this video Special IP addresses, part of CompTIA A+ (220-901) Cert Prep: 5 Networking.
- When we talk about IP Addresses, we have lots…and lots of them that are out there…but we do have some special IP Addresses.…So I want to cover these in this episode very very quickly.…The first one I want to cover is broadcast.…Now the classic broadcast is 255.255.255.255.…If one computer sends out that particular IP Address,…every computer on the local area network…is going to listen and take in whatever that packet is.…The second one I want to talk about is called loopback.…
So let's actually watch loopback in action.…If I want to access another computer,…I can go ahead and type ping,…and I'll get a reply back from it,…and that's what ping's all about.…There are situations where I might ping somebody,…there we go.…
So I get a ping and in this case it says…the destination host is unreachable.…So here's a situation where I'm worried…that I can't connect to this person.…Now I could make some assumptions here,…like I can assume they were down, might be one example,…but one thing I can do is I can actually,…you ready, ping myself.…
