How to order and set up a static IP address

Before ordering a static IP address, you must already have active internet service from CenturyLink. If you're a new customer, find out which speeds are available and order internet service before continuing.

Once you have internet service installed and running, you can use the static IP tool to lease static IP addresses. 

* Leasing a single static IP address provides an IP address to be used by your modem. If you need to assign an IP address to a device behind your modem, you will need to lease a block of IPs.

Port 25 filtering is enabled by default. If you are using your own email server, port 25 filtering should be disabled. You can disable or enable Port 25 Filtering using the static IP tool.

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.

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. This is only applicable to qwestoffice.net customers.

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. This is only applicable to qwestoffice.net customers.

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

1. Start by leasing a single static IP address using the static IP tool (see instructions in the section above).
2. Allow one full hour for your request to be processed.
3. Reboot your modem by unplugging the power cord and waiting for 3 minutes.
4. Plug the power cord back into your modem, then watch for the internet light to turn green.
5. Verify that your new IP address is visible by looking it up at http://www.whatismyip.com/. Once you've confirmed that, you're done!
6. If you are having trouble, contact tech support.

To setup Reverse DNS, log into the Static IP tool. Under Reverse DNS Mapping, click the View or change link and then fill in the DNS table as needed.

To cancel a static IP lease, log into the Static IP tool. Select "Delete IP Block" and then follow the instructions on the following screens. Don't forget to re-configure your modem after deleting your IP Block. Single static IP users do NOT have to reconfigure their modems.

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.
