Here's what one looks like for a host named 'raptor' after the Intel ISA:

$ cat /etc/hosts
# Loopback entries; do not change.
# For historical reasons, localhost precedes localhost.localdomain:
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

# 127.0.1.1 is often used for the FQDN of the machine
127.0.1.1   raptor.home.arpa raptor

# The following lines are desirable for IPv6 capable hosts
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
