No why not because theyre on different network

address and this subnet mask can this computer talk to my default gateway and my DNS server? No. Why not? Because they're on different network segments logically, k. The only way this host could possibly contact my default gateway or my DNS server is if we routed the data to it because it's on a different network and notice down here I don't even have a default gateway assigned. So APIPA's kicked in, I have an autoconfiguration IPv4 address assigned, sometimes you'll hear this referred to as a link-local address because it's only good on the local network segment. No default gateway is assigned. Really this is a useless address, it doesn't do a whole lot. So what do I do to fix this problem? Well there are two different options. One option would be to go in to the Network and Sharing Center down here and statically assign an IP address, a subnet mask, a default gateway and a DNS server address. I'm betting that if we do an ipconfig /all command which displays extended information about the network adapter that we will see that we don't even have a DNS server address assigned. Yep, notice under DNS servers I have a bunch of IPv6 link-local addresses configured, they don't work, there is no DNS server configured with these addresses and I don't have any IPv4 DNS servers listed.So I'd have to assign all four parameters. I'd have to assign the IP address, subnet mask, default gateway and DNS server IPv4 addresses before this would be able to communicate on the network. Now really that's not the best

solution because using static addresses is number one, time consuming to configure and number two, prone to error because we'd have to be very careful not to assign the same IP address to multiple hosts and the chances of that happening are pretty high especially if you have multiple people performing that task. The better option would be to contact the network administrator who's responsible for the DHCP server that's either down or unreachable and have them fix the problem. That's the resolution we're going to use in this demo. Alright so I have went and checked my DHCP server, found that it was down and fixed the problem. So at this point, let's do an ipconfig /release command. That will release all IP addressing information that was automatically assigned by APIPA because we don't want it anymore and now let's go out and get a new IP addressfrom the DHCP server that i just turned on. So I do an ipconfig command again and this time we type renew. The release command releases whatever DHCP leases may have been assigned and also as you notice release the APIPA address. The renew option on the other hand tells ipconfig to go out and send another DHCP discover packet,locate a DHCP server and get new IP addressing information. Hit Enter. Wait just a minute while it communicates with the DHCP server and everything is good, we got a new real IPv4 address now, the correct subnet mask, the correct default gateway for this network segment. If we do an ipconfig /alland scroll up we should see that we now have a DNS server configured as well and that's the correct IP address, 10.0.0.1. And if I notice my network icon down here in the

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
