When any client on your LAN asks your DNS server for an address, the DNS server makes a query to external DNS servers, caches the results, and tells your client the answer. The next client on your LAN to ask about the same address, will be told the cached answer. Telling your clients which DNS server to use is another matter. > What if my computer is shut down for the night, will the others go > on and use the ISP dns? If you had, say your DNS server at 192.168.0.1, and clients configured to only use 192.168.0.1 as their DNS server, then they're reliant on 192.168.0.1 always being there. If you had configured your clients with a list of DNS servers, they'll query one of them, only trying other ones when they don't get any response. I don't know what determines which DNS server will get queried out of a list, whether Fedora will do it sequentially down the list, or randomly. Nor whether any subsequent queries will use the same server as the last time, or pick another one each time. > > The complications are: If your other computers are assigned addresses > > by DHCP, then you have to put overrides on the individual client > > configuration, or configure the DHCP server to say that *YOUR* DNS > > server is the LAN's DNS server to all computers that ask it for an > > address (I do this with mine). > DHCP via the router was the path of least resistance, they get > static assignments, but I could set them up with fixed addresses if > that is necessary.

My LAN has a mixture of clients with fixed and dynamic addresses, some are fixed by hand configuring those machine's network configuration, on those machines. Others are fixed by configuring the DHCP server to always give the same IPs to the same machines. In any case, they all use the same DNS server. The manually configured machines had the local DNS server manually set in their config. All the rest were told to use the local DNS server in the data that the local DHCP server gives out. -- [tim@localhost ~]$ uname -rsvp Linux 3.6.6-1.fc17.x86_64 #1 SMP Mon Nov 5 21:59:35 UTC 2012 x86_64 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
