MSDN recommends using GetAdaptersAddresses instead of GetAdaptersInfo on
Windows XP and later. This is because it transparently supports IPv6.
Windows XP and later. This is because it transparently supports IPv6.
It is quite straightfordward to get the current ip address(s) from the
FirstUnicastAddress linked list but I cannot see a way to get the IPv4
subnet mask. Is this possible with GetAdaptersAddresses?

With ConvertLengthToIpv4Mask() for OnLinkPrefixLength - inet_ntoa()
(Vista)

Thank you. This makes sense now.
Unfortunately my code needs to work on XP so it's back to using
GetAdaptersInfo. Shame that this obvious feature was only added in Vista!
