           Summary: VisualHostKey and host key fingerprint aren't
                    displayed when host's IP address is changed
           Product: Portable OpenSSH
           Version: 5.2p1
          Platform: ix86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ssh
        AssignedTo: unassigned-bugs at mindrot.org
        ReportedBy: tom at holizz.com


My home server's IP address changes frequently, and the first time I
ssh into it after it changes, neither the host key fingerprint nor the
VisualHostKey are displayed, meaning there's no way for me to verify
that I'm sshing into my home machine, and not another machine that's in
my known_hosts.

% ssh holizz.ath.cx
Warning: Permanently added the RSA host key for IP address
'92.3.96.217' to the list of known hosts.
