I'm sure this is very simple, I just can't seem to learn Regexes: I have been given the chore of taking a DB table of client records, which has a field called IP address. Whenever a client logs onto our site, I'm supposed to display the IP address they logged on from THE LAST TIME they visited, as a security measure. This field is a MySQl varchar(30). Since this field was added at table creation, but not used until recently, many of the fields contain NULLs or junk text. Can someone point me in the direction of creating REGEX to test whether an IP address is valid. (Valid in the sense of syntax i.e. 192.168.24.20 is valid, but 277.22.49.75, or 65.23 is not)?
