Hi there,

Does anyone know the technical diff between the following:

http://localhost
http://127.0.0.1
http://loopback

The above three address does the same thing, but is there any diff b/w them (apart from the spellings)?


Thanx

127.0.0.1 doesn't need any translation/lookup to function. It's a loopback address that is assigned to the local TCP/IP device by the definition of the protocol. The other two are hostnames (aliases) for 127.0.0.1 and require a quick lookup/translation.

One thing to note is that an IP address is distinctly an IP address. So, if you type it in your address bar, your browser generally won't mistake it for a search string. On the other hand, FF and IE both tend to mistake localhost and loopback for search queries, and you end up looking at something like localhost.com.

But, that 2nd part isn't really a technical difference.

That info helped me.

Thanx
