Could it be possible that you have "options inet6" in your
/etc/resolv.conf file? This options causes calls for only AAAA records at
first and then if they fail, use A records.
According to Mr. Stevens (Unix Network Programing Vol 1
chapt 9.4) this option, or having the env. variable RES_OPTIONS=inet6 set
will cause the behavior you are describing...

Hmmm... I don't know but it seems that ssh -4 set's its own family to
AF_INET in all of it's calls to gethostbyname() rather than AF_INET6.
Thereby telling the resolver to only return A records....
