Expire Stale Addresses

IP addresses can be automatically assigned by Dynamic Host Configuration Protocol (DHCP), and addresses can become out of date. You can expire stale, out-of-date IP addresses so they are refreshed. You also can change the frequency of DNS name updates when you edit an address.

The program checks the DNS server and refreshes the DNS name for with each expired address.

Follow these steps:

1. Display the Address-Hostname Configuration page:
   1. Select Administration from the NFA console menu.

      The Administration page opens.

   2. Select Reporting: Addresses from the Administration page menu.

      The Address-Hostname Configuration page opens.

2. (Multiple domain environment only) Select the domain that contains the address you want to refresh.
3. Click List.

   A list opens, which shows the addresses for the selected domain.

4. Click the check box next to each address that you want to expire.
5. Click Expire, then confirm the expiration when the prompt opens.
