v Ns TTL

1.3.6.1.4.1.22.65.1.2.6.1.7.4.1.3

The time to live (in seconds) of this entry in the nameserver table. If the entry has been dynamically created by the nameserver protocol, the TTL will be a non-zero value indicating its remaining lifetime. Upon expiration of the TTL the entry is automatically deleted from the table. If the entry was created by a network administrator, the entry is considered 'permanent' and the value of its vNsTTL will be 0.
