How to set up a static IP address

When you lease a static IPv4 address, those addresses have 'derived IPv6' addresses associated to them, so there is no need to order anything else. But, you will need to enable IPv6 on your modem.

Customers with a dynamic IP address cannot turn off port 25 filtering.

If you have leased static IPs and need assistance with port 25 filtering, or if you would like to lease static IP addresses from CenturyLink, please contact us.

The lease on static IP addresses continues until you either choose to delete them from your account, or until you cancel your CenturyLink internet service.

For qwestoffice.net customers only: Only one domain name can be assigned to a specific IP address. For example, ftp.mycompany.com and www.mycompany.com are considered one domain name. However, www.yourcompany.com and www.mycompany.com are considered two separate domain names and both could not be assigned to the same static IP address.

Note that moving or upgrading your service will usually require a change to your static IP address.

Please contact us to cancel a static IP lease. If you had a single static IP, you do not need to reconfigure your modem. Customers with an IP block will need to re-configure the modem.

If you cancel a single static IP lease, you do NOT need to reconfigure your modem.

If you cancel an IP block lease and your modem was configured for that block, you will need to reconfigure your modem to use a dynamic IP. To do this, configure your modem's WAN settings, following the instructions for PPPoE Setup > PPPoE with dynamic IP.
