Internet Provider Security (IPS) tags are used by domain registrar to administer a domain name registration service and related Domain Name System (DNS) services. An IPS tag is the label that applies to each registrar that registers domains in the country-code top level domain "uk" and is required to transfer domain names from one registrar to another.
You cannot switch a domain name without the IPS tag.
