Sorry to bother everyone, but AFAICT this discussion kind of
disappeared. Did I perhaps get dropped from CC? I'm interested to know
what the final resolution of this is.

My own thought would be:
"host" means the thing you intended to connect to: a unique identifier
for the server, probably (usually) the hostname, and also the thing
that goes in a certificate. Should (probably) never be omitted.

"hostaddr" means the thing you actually send your TCP SYN packet to:
maybe an IP address if you want to save a DNS lookup, maybe even
"localhost" if you want to use an SSH tunnel (or even some other
hostname if you have an even stranger tunnel set up), but purely a
"network-layer" thing about *how to get to* the server, and not a
"user-trust-layer" thing about *who the server is*. If omitted,
defaults to being equal to "host".

I don't know if that's what was intended, but that's what I thought
they would mean.
