This regex should resolve that. (messy as heck but does the job)

(?:(?:(?:(?:2[0-5][0-9])|(?:1[0-9][0-9]))|[1-9][0-9]|[0-9])(?<![^1-2]00)(?<!25[6-9])(?<!2[6-9][0-9])\.){3}(?!00)(?!25[6-9])(?!2[6-9][0-9])(?:(?:(?:2[0-5][0-9])|(?:1[0-9][0-9]))|[1-9][0-9]|[0-9])

also, the one on the site gives a false positive for these additional IPs 255.255.255.256, 9.9.9.256, 1.1.001.1, 1.1.1.00, 1.00.2.2, 00.1.3.3
