if it's stable but has multiple valid path (ex: acme-v1.ca.com and acme-v2.ca.com) , would server need try for both subdomain and lookup every possible valid path?

From my understanding, under ACME we treat that entire accountURL as the userID. So I think that URL will need to be stable.

    duce don't have full accounturl that used to craft challenge
    subdomain:

    like boulder (what Let's encrypt uses) allows to accessed from
    mulitple
    path ex:

    "accountURIPrefixes": [
    "http://boulder.service.consul:4000/acme/reg/";,
    "http://boulder.service.consul:4001/acme/acct/";
             ]

      , and pebble and smallstep do not have host in config but allow
    any ip
    or domain pointed to them and reflect them to create link to
    account/order/ect

    would only using userid part of accountURL (ExampleAccount) from
    https://example.com/acme/acct/ExampleAccount have problem? while it's
    trivial to extract from hash to accounturl as accountID was
    autoincrementing counter, but was there are so few large acme
    provider
    it was trivial to make rainbow table anyway.
