OK, if the double colons are correct, then that is almost certainly the problem:

  $ ssh does-not-exist
  ssh: Could not resolve hostname does-not-exist: No address associated with hostname
  $ ssh does-not-exist:
  ssh: Could not resolve hostname does-not-exist:: No address associated with hostname

Can you give us a hint as to the format of your remote URL? This "works":

  $ git push does-not-exist:repo.git
  ssh: Could not resolve hostname does-not-exist: No address associated with hostname

in the sense that it looks up the right hostname (which is of course nonsense, but note the single colon in the error message). So does:

  $ git push ssh://does-not-exist/repo.git
  ssh: Could not resolve hostname does-not-exist: No address associated with hostname

but this does not:

  $ git push ssh://does-not-exist:/repo.git
  ssh: Could not resolve hostname does-not-exist:: No address associated with hostname

(note the doubled colon). v2.3.3 did strip off that extra colon, but I am not sure the URL above (i.e., a colon with no hostname) is actually sane. IOW, it may have happened to work in older versions, but I'm not sure we would want to promise to keep it working.

Can you show us what your URL looks like, obfuscating the names but keeping the syntax the same? Also, are you using the "insteadOf" config syntax at all (which could easily lead to funny splicing, I imagine).

If the extra colon is indeed the problem, I don't think the DNS setup is relevant. The name git is feeding to ssh is bogus.
