What are the problems if the hostname is changed from 127.0.1.1 to 127.0.0.1?

Question

SQL Server

As part of the task with HBase , I had to change the devserver in /etc/hosts:

127.0.0.1 localhost<br>
127.0.1.1 dev<br>

On:
127.0.0.1 localhost dev<br>
What does it threaten? I unfortunately nifiga in network routing do not understand.

Ubuntu 11.04 server for developers, access from local network. There will be LAMP, web projects, local domains (*.dev), respectively bind9.

Answer 1

Nothing should. You can write another 20 similar aliases for 127.0.0.1 and you won't notice anything.

Answer 2

None :)
127.0.*.* - and so it will ping in any case)

Answer 3

Nothing will be special. Just do:
127.0.0.1 localhost
127.0.0.1 dev
I don’t remember offhand, but some systems didn’t read hosts like yours.
