IPS Tags

The IPS tag, also known as the provider tag or registrar tag, is the registration identification for a .uk domain. The tag identifies the provider where the domain is registered.

This protects .uk domains from unauthorized transfer requests and has a function similar to that of Authorization codes with transfers of non-UK domain extensions (such as .com or .net).

The IPS tag procedure applies to these domain extensions (among others):

  • .uk
  • .co.uk
  • .org.uk


Each .uk domain registered with IONOS uses the IPS tag 1AND1, 1AND1-IONOS or IONOS. As long as the IONOS IPS tag is set to 1AND1, 1AND1-IONOS or IONOS, all domain transfer requests are ignored.

  • Transfer from another provider to IONOS:
    If you transfer a .uk domain from another provider to IONOS, you must change the IPS tag to 1AND1, 1AND1-IONOS or IONOS with your other provider.
  • Transfer from IONOS to another provider:
    If you transfer a .uk domain to another provider, you must change the IPS tag at IONOS to that of the new provider tag (provider/registrar).
