Using 127.0.0.2 instead of 127.0.0.1

[richyama]

Hi everyone,

Just have a question. Hoping someone can help me out.

At work, our client-server based software program on our server uses 127.0.0.1 to connect to the database. If I switch this to 127.0.0.2, will that cause any problems when connecting to a database? I tried it and it works with no data lost but I'm not quite sure how loopbacks work and I just want to make sure no data is lost if I change this setting.

I need to use 127.0.0.2 to resolve an issue with services being used on 127.0.0.1

Thanks!

The standard is that all of 127.0.0.0/8 is reserved for loopback and should work. The easy test is to ping the address you are interested in and see if you get a response.

This article -- http://www.tech-faq.com/127-0-0-1.html Says that any 127.x.y.z would work. But all the services on the localhost should have unique port numbers. It sounds like you need to change a port number and not the loopback IP address.
