$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 nice.org

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

I know 127.0.0.1 is the loopback address.
What does 127.0.1.1 mean ?

It doesn't really mean anything in particular (it's just another IP in the 127.0.0.0/8 block).

The reason it's used as the IP for your hostname is explained in Section 10.4 of the Debian Reference Manual.

Quote:

Some software (e.g., GNOME) expects the system hostname to be resolvable to an IP address with a canonical fully qualified domain name. This is really improper because system hostnames and domain names are two very different things; but there you have it. In order to support that software, it is necessary to ensure that the system hostname can be resolved. Most often this is done by putting a line in /etc/hosts containing some IP address and the system hostname. If your system has a permanent IP address then use that; otherwise use the address 127.0.1.1.
