If speed is an issue, it should be possible to do asynchronously, e.e., linkify in grey
and do the DNS check, then change the color when the DNS answer comes back.  In a lot of
cases the answer will be in the local DNS cache so it'll be pretty quick.

In systems like Slack, if you enter a URL, it fetches the page and
decorates the URL with info about whatever the URL points to. People
seem to be used to that.
