- The IPv4 general name form followed by an /etc/hosts file fragment example for IP address 10.11.12.13 is:

host.auth.ddd.ccc.bbb.aaa.in-addr.arpa
# /etc/hosts example
10.11.12.13 foo.bar.com.auth.13.12.11.10.in-addr.arpa

- Pre-pend a fully qualified host name before other mappings to the same address. For example, in /etc/hosts format:
