Long time lurker but this is my first post to the list. :)
I was wondering if there was a technical reason why MAXNS is set to 3
for the libc resolver in resolv.h (inherited from BIND and others
followed suit (like glibc)). Everyone states MAXNS is set to 3 in
documentation but no one says why it is 3 (if it's not arbitrary) by
default.  :)
