Hi, the module Network.Socket provides 'getaddrinfo' only if IPv6 support is enabled. That surprises me because, as far as I know, there is nothing IPv6-specific about that function. Does anyone know why that choice was made? Best regards, Peter

The RFC that introduced it did so for the purpose of supporting IPv6.
The configure checks don't care if IPv6 is actually enabled, merely that
there's a working IPv6-capable API. You can then use getAddrInfo on
IPv4 or IPv6 addresses as you wish.

Meanwhile, I found out that the configure check that determines whether IPv6 support is available or not looks like this: dnl -------------------------------------------------- dnl * test for getaddrinfo as proxy for IPv6 support dnl -------------------------------------------------- AC_CHECK_FUNCS(getaddrinfo) Apparently I was worried for no reason. :-) Thanks for responding, Bryan.
