DNS Different IP for Different Port -
is possible assign different ip different port?
such as:
http://example.com:80 -> 123.456.789.012
http://example.com:90 -> 987.654.321.098
is there way this?
you can use dns srv records associate hostname (and thereby address) and port number service name, virtually no web browsers or other http clients query srv records.
so, in practice, no.
even srv records, cannot solve problem in question stated. srv records won't resolve http://example.com:80/
, http://example.com:90/
different addresses, because specifying port number manually overrides srv record , queries address (a , aaaa) records directly. srv records (if browsers bothered query them!) resolve http://a.example.com/
, http://b.example.com/
different addresses (or same address) , different ports.
