Domain names

Domain names

A domain name is one of the components of the internet’s transport layer, being the internet’s naming and addressing system.

Each computer or device that is connected to the internet is identified by an internet protocol address, commonly known as an IP address, that comprises a long string of numbers. As people find names easier to memorise than long strings of numbers, the domain name system evolved to help people locate resources on the internet.

Registration of domain names

Domain names must be registered. Following registration, the registered name holder can control that domain name.

Domain names are a valuable business asset. Once a person registers a domain name, it prevents another person from registering the same domain name, unless the later applicant has grounds to dispute the registration of the domain name by the original registrant.

For more information on background, registration and dispute resolution, see Practice Note: Domain names—background, registration and dispute resolution.

Each country has a country code top-level domain (ccTLD) with an entity responsible for managing registrations in that ccTLD. For information on the registration and use of domain names at the ccTLD registry

Ofcom launches third consultation on notification guidance for online safety fees regime

Ofcom has launched its third consultation to support implementation of the online safety fees regime under the Online Safety Act 2023 (OSA 2023). The consultation sets out proposed technical guidance to help providers of regulated services comply with notification requirements.

Providers are required to notify Ofcom in certain circumstances, unless exempt, and submit evidence detailing their regulated services and QWR. The Online Safety Act 2023 (Fees Notification) Regulations 2025, SI 2025/747, were laid before Parliament on 26 June 2025 and are expected to come into force on 14 September 2025. Responses are sought by 1 October 2025.

CAP extends advertising code scope to cover non-UK based licensed operators

The Committee of Advertising Practice (CAP) has extended the scope of its Code to ensure consistent regulation of online advertising. Effective from 1 September 2025, the Code now applies to non-paid-for online marketing communications directed at UK consumers by advertisers who are subject to licensing conditions from UK public authorities or bodies mandating compliance with the CAP Code, even if those advertisers lack a UK-registered company address. This change specifically brings into scope social media content marketing by licensed gambling operators on their own channels, enabling the Advertising Standards Authority (ASA) Council to apply consistent rulings across such advertisements irrespective of the operators’ location. CAP has confirmed that the extension does not apply to other advertiser categories without a UK-registered address. Stakeholders are invited to submit comments on the impact of this change until Monday 1 December 2025, ahead of a formal review.
