I have several hosts defined in ~/.ssh/config like so:
Host myhost
HostName myhost.luo.ma
User myuser
Port 5555
Something changed, because now when I type "ssh my[tab]" I get "ssh
myhost.luo.ma" instead of "ssh myhost" which then fails because it
isn't using the port specified in ~/.ssh/config.
I _think_ it has to do with the ~/.ssh/known_hosts file, because if I
delete the entry from that file, tab completion seems to work as I
expect.
I've looked around for a solution, and it appears that if I add this line:
HostKeyAlias myhost
then the short hostname gets uses for the known_hosts file, but I'm
not sure if that's a "good" solution or not.
Is there a way to tell zsh to only do tab-completion for ssh out of
~/.ssh/config and ignore ~/.ssh/known_hosts ?
Thanks!

Tweak your Host entry to include the FQDN, e.g.:
Host myhost.luo.ma myhost
I don't think the order matters. I personally like to put the FQDN
first and then aliases after. (I pattern off of the hosts file.)

I think that's functionally (part of) defining a new host by the
alternate name and recognizing the alternate name's host key.
I'd suggest trying adding aliases to the Host entry, as described above.
I've done things like this:
Host FQDN alias project<#>-db customer<#>-db current-problem-child
The project<#>-db is nice so that I can easily ssh into a project's DB
server without needing to mentally translate to the host name. I can
literally do the following:
ssh project815-db

I'm sure there is a way. I don't know what it is. I've not dealt with
this issue in about 6 years.

I get satisfactory tab-completion by setting Host to a name but Hostname
to an IP address. Seems to work.
Best wishes,
