AhoDNS is a tiny and simple forward-lookup only DNS server written in Go using https://github.com/miekg/dns .
$ ./ahodns -listen="udp:127.0.0.1:8053" -ttl=300 RECORDFILE
By default it tries to listen on 127.0.0.1:8053. To test with this configuration, do the following:
$ dig @127.0.0.1 -p 8053 aho
It is a simple text file that contains a pair of a domain name and an IP address in each line. Beware that the values are separated by a tab, not spaces!
aho1 127.0.0.2
aho1 127.0.0.3
aho2 127.0.0.4
aho2 ::ffff:127.0.0.5
