Abstract
Various techniques for managing backup for domain nameservers are disclosed herein. In one embodiment, a method includes receiving a nameserver record associated with a domain name. The nameserver record containing addresses of an active nameserver and a passive nameserver. The method also includes determining if the active nameserver is reachable by contacting the active nameserver based on the address of the active nameserver in the nameserver record. In response to determining that (i) the active nameserver is unreachable and (ii) the nameserver record does not include an address of an additional active nameserver, the method includes contacting the passive nameserver for resolving the domain name based on the address of the passive nameserver in the nameserver record.
