Motivation: Due a change introduced in 68105b257d915d8a0cb7b2acd9061661666537b6 we incorrectly skipped the usage of nameservers in some cases. Modifications: Only fetch a new stream of nameserver if the hostname not matches the original hostname in the query. Result: Use all configured nameservers.
