Hi there, it would be a minor improvement, but much useful depending of the case... Mysql uses "%" as wildcard for remote authenticating host, so: - 172.16.0.1 is valid - 172.16.0.% is valid (C network) - 172.16.%.% is valid (B network) - 172.16.0.0/255.255.255.0 is valid (another way to enable a C network in MySQL) Problem is currently we cannot enable networks for remote access. I have seen plugin is using FILTER_VALIDATE_IP php function, which cannot validate a network range, for example 172.16.0.0/24. Possible suggestions: - discard using FILTER_VALIDATE_IP and just use regex, allowing "%" characters. - discard using FILTER_VALIDATE_IP and just use regex to validate IP, allowing also network masking, for example: '172.16.0.0/255.255.255.0' Cannot tell about regex on ipv6...
