Configure the forward and reverse lookup zones for dynamic updating West free webcam site sex
If you’re running DHCP and DNS on your NAT router, now would be a good time to disable it.
How to do this varies depending on the type of router, but if you’re willing to set up your own DHCP and DNS services on a Linux server, you can probably figure it out.
Don’t worry about filling in the names for any DHCP-assigned hosts, as the dynamic update setting we’ve just finished with will take care of allowing DHCP to add in its own hosts without you having to deal with it. Each statically-addressed host gets an A record so that the server knows how to correlate its name with its IP address. The thing to notice about the reverse zone is the name of the domain we’re working with: is used as the domain for reverse lookups for historical reasons, because DNS reverse lookups use a method codified back when was actually a working domain.BIND9 is a Unixy-beast—it’s a powerful but cryptic application with a rich and potentially complex configuration.Still, all we’re going to do is set up three simple zones—that is, three separate administrative blocks—and add a few options so that servers on your LAN can use the DNS server, so the resultant set of config files won’t be too bad at all.Alternately, instead of cutting and pasting in the contents of is more secure.
However, this is just a home DNS server, so it’s not really necessary. # Now we add A records for the non-DHCP hosts in the domain: server_1 A .21 server_2 A .22 server_3 A .23 ...
However, the feature set and functionality of these cut-down DHCP and DNS instances are almost always too limited to handle more than the simplest of network designs; sometimes, you need to be able to do more.
