Block sites accessed by it's IP address

abougher
How would one go about blocking URLs that contain an IP?

Example:

hxxp://www.ok-website.com = good
hxxp://64.50.50.123 = blocked (unless added to exceptions)

I have tried using the "Block Uncatagorized" option but, that does not work in this case and is really quite unwieldy in general.

Gateway: ASG320
Firmware: 8.301

Thanks in advance.

    I believe I have figured it out.

    In Web Security->Web Filtering->URL Filtering->Additional URLs/sites to block  add the following RegEx:

    ^http?://(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)

    This excludes 0-255 for each of the 4 numbers of a IP address.

    Then in Web Security->Web Filtering->URL Filtering->Always allow these URLs/sites add the IP addresses that are allowed.

    In testing, this appears to work as advertised.
