Our InternetServer, =liberty=, provides DNS (Domain Name System) service. We use ISC BIND. liberty is the SOA nameserver for the =gnhlug.org= domain. At the TLD (Top Level Domain) servers, there are NS records which delegate authority for =gnhlug.org= to liberty and its peers. This is how other DNS resolvers in the world find out which nameservers to ask about the domain. liberty is configured as a BIND master server for the =gnhlug.org= domain. Some other name servers are slaved to liberty for the domain. As of this writing, the only active slave is =rogue.codemeta.com=. It is delegated from the 2LD and listed in the zone file. We are in the process of bringing up some !DynDNS slaves as well. These will be =ns2.mydyndns.org=, =ns3.mydyndns.org=, =ns4.mydyndns.org=, and =ns5.mydyndns.org=. They are listed in the zone file, but have yet to be delegated from the 2LD. BIND also provides a full-service, caching resolver for the software running on liberty. Only liberty itself is permitted to make use of this resolver. Other IP addresses are denied. This is accomplished via =allow-querry= statements in the =named.conf= file. BIND runs chrooted under =/var/named/=. =linux.codemeta.com= used to be an authorative nameserver for the =gnhlug.org= domain. It does not currently have anything to do with DNS for =gnhlug.org=.
