Excuse this basic question,, just why are we using telnet anyway? Aren't we
supposed to be using ssh?
I understand that will not answer the initial question, but if you use ssh
does the same thing happen? what about rlogin?

Sure, your /etc/hosts file contains mapping for IPv4 addresses, but
probably not for IPv6. As Russ suggested, use tcpdump to see if
queries are originating for AAAA records from the machine you are
telnetting into.
