Hi developers,
Here is a regular expression recommendation that will match private IP
addresses.
This matches only valid rfc1918, local loopback and the link local block IP
addresses.
(?:(?:10|127)\.(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)|192\.168|169\.254|172\.0?(?:1[6-9]|2[0-9]|3[01]))(?:\.(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)){2}
I also included this as an attachment since mailing may break it.
This regex returns 9 IP addresses against my test bed (Private IP
addresses.txt).
It will return a list when used with re.findall and will return a match
object that will fit w3af code in privateIP.py when used with re.search.
PS: To get an exact match, \b might be added to both sides of the
expression.
Best regards,
Sertan
