Domain Lock

Nominet Domain LockWhat is Domain Lock?

Domain Lock is a chargeable service from Nominet that allows domain names in the UK namespace to be locked at the Registry level. This means that no changes can be made to the Domain Name System (DNS) configuration unless unlocking is explicitly requested by a pre-authorised representative through an additional authentication process.

This additional security layer provides peace of mind that changes cannot be made to the DNS without identity being thoroughly authenticated.

Who is Domain Lock for?

Domain lock is for anyone who is concerned about the reputational damage that could occur if their website is hijacked. This service would be most suitable for high profile brands, financial services, media companies, and high traffic websites but can be applied to any domain in the UK namespace.

Why is Domain Lock important?

Recent years have seen increasing occurrences of high profile DNS hijacking: this occurs when an attacker gains unauthorised access to registration data for a domain name and modifies the data for their own purposes.

This could result in traffic being diverted away from the intended destination to a malicious website, allowing the attacker to display offensive or objectionable content, or to steal a user’s credentials by setting up a phishing website. If this happens it can significantly disrupt an online business as well as causing damage to the reputation of not only the registrant but also the reputation of their registrar.

How does Domain Lock work?

When Domain Lock is applied to a domain, it is locked down by Nominet. This means that no changes can be made by anyone:

  • Prevents nameservers from being changed
  • Prevents the registrant name and/or address and contact details from being amended
  • Prevents the domain from being transferred to another registrar

What will Domain Lock cost?

Each Domain Lock will cost £75+VAT per domain per annum and will be invoiced in 12 monthly instalments at £6.25+VAT per month
