The -F option should tell you what is in known_hosts; the hostname can
be a name or an IP address. If
ssh <name>
is used two lines are entered into known_hosts and two invocations with
'ssh-keygen -R' are needed to clear the file. With
ssh <IP address>
only one line is produced.
Could this explain your observation?
