Hello, you can use cfgutils or siputils.
I plan to add some more IP/dns related functions for config usage (no timelines yet, though):
- netmask comparison using pseudo-variables - dns resolver for querying and accessing the result in config So starting a new module like 'ipops' might be a good solution, as well. Cheers, Daniel On 4/27/11 12:50 PM, Iñaki Baz Castillo wrote:
Hi, AFAIK SR doesn't provide a way to binary compare two IPv6 (correct me if I'm wrong). About IPv4 comparison, I assume it's compared as a string: if ($rd == "1.2.3.4") so it works. But in case of IPv6 it would not work as the same IPv6 could take different (but equivalent) representations: "1080:0000:0000:0000:0008:0800:200C:417A" "1080:0:0:0:8:800:200C:417A" "1080::8:800:200C:417A" I'd like to add a function to perform IPv6 binary comparison (as I've already coded it in a personal project), could you please tell me in which module should it take place? I mean something as: -------------------------------------------------------------------------- compare_ips(ip1, ip2) Returns 1 if both IP's are two equal IPv4 or two equal IPv6. Returns -1 if both IP's are valid but not equal. Returns -2 if at least one give IP is not a valid IPv4 or IPv6. Parameters: - ip1: An string of pv containing a IPv4 or IPv6 in text representation. - ip2: An string of pv containing a IPv4 or IPv6 in text representation. -------------------------------------------------------------------------- Thanks.
