Android Question [SOLVED] Checking IP Address input sanitization?

[techknight]

Does anyone have an example on how to inspect the input of a dialogbox for an IP Address properly inputted?

Making sure there are the proper periods in the proper locations, whether it has numbers and not letters, etc...

any thoughts?

Thanks.

Regex?

^(?:[0-9]{1,3}\.){3}[0-9]{1,3}$

or more complete

^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$
