Hi.
This is kind of weird, so I want to see if anyone else has noticed
this or has a solution to it.
If I use telnet or ssh (there might be more programs,
but I have only noticed these two so far), and supply a hostname to it,
my machine is constantly requesting AAAA records, and finally after
75 seconds it requests and receives an A record from the nameserver.
Using ssh -4 or telnet -4 makes it work right away (of course), but
I don't want to have to type that all the time. [program] ipv4address
also works.
Logs are attached..

This happened about a month ago but it fixed itself after a few hours
so I thought it was a name server problem until it happened again today...
It happens with any nameserver I try.
Any ideas??
