To probe network adapter properties in IPv4, we can use SIOCGIFONF, SIOCGIFNETMASK etc. On HP-UX and Solaris, the IPv6 equivalents are SIOCGLIFONF, SIOCGLIFNETMASK.
Does AIX support these ioctls (perhaps with an APAR) or are they called something different?
A pointer to a standards document would be helpful - I googled but didn't find anything.
IBM's website implies the standard SIOCGIFCONF on AIX like Linux is IP family independent as it uses struct sockaddr.
