Understanding your IP address

Whenever you go online, your router or modem is given an IP address. Your IP is like your phone number, unique to you and used as a way to identify and reach you.

Your IP address will either be dynamic or static. Dynamic means you're given a different IP each time you connect to the Internet. Whereas static means you'll be given the same one each time.

All our current broadband products are given a dynamic IP but you'll have the option of changing to a static one. If you're using an older product, take a look at our broadband product archive for more about your IP. If you're not sure what you've got, check Connection Settings, under Manage Account in the Member Centre, or see the question below.

It depends on the broadband package you’ve got.

  2. Go to Connection Settings.

  4. To switch from a dynamic IP to a static IP, click Activate your Static IP. If you already have a static IP and would like to switch to dynamic then please raise a Ticket or call our Support Team on 0800 432 0200 or 0345 140 0200.
  • There's a £5 setup fee to start using a static IP if you’ve got home broadband and your package allows you to switch IPs.
  • You'll need to reboot your router before you’ll see any change.
  • If you remove a static IP, you probably won’t get the same address if you switch back again.
  • The option to choose a static IP won’t show up for accounts that aren’t able to switch between the two.

You'll need to change to a broadband package that allows you to switch IPs. To do that, just go to the Product Change Tool and choose a package that has a static IP.

You can get an IP block if you’ve got business broadband. It’s when you need a range of IPs (either four or eight), so you can assign different ones to different devices. It’s handy if you’ve got several different devices or services each requiring a public-facing IP address, like a firewall on one and an SSL website on another, because you won’t be able to use things like port forwarding or Network Address Translation (also commonly called NAT addressing).

To get a 4-block IP:

  1. go to the Help Assistant and select IP Addresses
  2. In the text box, let us know why you need a 4-block IP and why you can’t use port forwarding with your set-up (this’ll help us understand what you need us to do)
  3. Click Send your question to the support team and we’ll be in touch.

To get an 8-block IP:

  1. go to the Help Assistant and select IP Addresses
  2. In the text box, let us know why you need an 8-block IP. You'll also need to fill in a Ripe form and attach a network diagram listing each device that needs a public-facing IP
  3. Click Send your question to the support team and we’ll be in touch.

If you need help with any of that, just let us know.

Important information:

  • IP blocks will only be provided if the requirement cannot be met using NAT, Port Forwarding or Virtual hosting configurations.
  • Some broadband packages are not eligible for an IP block.
  • After completing this form you will also need to provide a network diagram listing each device that needs a public-facing IP.
