- DNS resolves Fully Qualified Domain Name (FQND) to IP addresses
- Host send their DNS queries to a DNS server usually over UDP port 53
- On a PC, the Nslookup command delivers FQND to IP address
- DNS commands to set up a router client to lookup FQND
- #> ip domain-lookup
- #> ip name-server x.x.x.x
- #> ip domain-name letnet.net (primary domain name)
- #> ip domain-list letu.edu (additional DNS suffixes to search)
- Setup router as DNS server, usually done by windows server
- #> ip dns server
- #> ip host (hostname) x.x.x.2 (address records)
- #> ip host (hostname.letnet.net) x.x.x.2 ; etc.
