188体育

You must contact the Government Digital Service (GDS) to get a domain name for your service on 188体育.

You should do this after working with GDS to agree a start point for your service. This will usually be a start page.

You must only advertise the URL (or short URL) of your 188体育 start point. You must never advertise any other URL for your service anywhere.

This guidance only applies to service.gov.uk domains. If you need a non-service domain, for example for organisational email, follow the guidance on naming and registering government websites.

After your alpha assessment

Once you鈥檝e planned a start point for your service, you鈥檒l need to agree a service domain name with GDS.

Your domain name should describe your service, rather than mention your department or agency - for example, apply-budgeting-loan.service.gov.uk.

You鈥檒l need to follow the:

• guidance on naming your service
• URL standards for 188体育
• guidance on naming and registering government websites

Contact GDS at [email protected] to request a domain name.

In your email you should briefly describe:

• what your service does
• who your users are
• what user needs you will meet

GDS may ask for more information about your service before agreeing an appropriate domain name with you. The name will likely be similar to the title of your 188体育 start point.

Choose where you鈥檒l host your DNS

Once you鈥檝e agreed a domain name for your service with GDS, you鈥檒l need to choose a DNS provider or arrange to run your DNS servers yourself.

A DNS provider will publish your DNS records on the internet so that users can connect to your service.

Your provider will give you several DNS name servers. As soon as you have these, send the details to [email protected] so GDS can request the delegation as soon as you鈥檝e passed your beta assessment.

You鈥檒l need to provide at least 2 nameserver records for your domain. GDS recommends you provide 4.

DNS is often a single point of failure. Consider using multiple suppliers - that way, if one ever goes down, people will still be able to find your service.

You can search for DNS suppliers on the Digital Marketplace. If you do not know which suppliers to choose, ask for advice from technical staff in your team or organisation.

Ensure users start their journey on 188体育

You should make sure users always start their journey on the 188体育 start point for your service.

To ensure users start their journey on 188体育, you need to set up your service domain correctly. You must:

• redirect users to the 188体育 start point if they go straight to a page on the service鈥檚 domain
• tell search engines not to index pages on your domain

Telling search engines not to index pages

You can either:

• serve a meta tag on every page with the value: noindex, nofollow
• use a X-Robots-Tag response header with the value: noindex, nofollow

Do not use a robots.txt file to prevent crawling of your service. This will prevent the crawler from seeing the noindex directive, so pages on your service may still appear in search results.

If users need to access your service directly

There are occasional exceptions to these rules. Contact [email protected] if you think users need to be able to access pages on your service domain directly.

After your beta assessment

Your service can begin using the service domain after:

• you鈥檝e passed your beta assessment, and
• your department鈥檚 assessment team has shared the assessment report with [email protected] and [email protected]

Contact [email protected] after your assessment to request the domain delegation. GDS will then delegate the service domain. This can take up to 5 working days.

Once GDS has finished the delegation, your team will be able to manage where the domain name points to.

You鈥檒l also need to contact the GDS content team to let them know to publish your service start point and feedback page.

Set up subdomains

Once you have a domain name, you can set up subdomains (for example, for a staging environment or static assets).

Find out more about managing domain names.

Set up security certificates

Once you鈥檝e set up your DNS delegation, you鈥檒l need to get TLS certificates from a certificate provider.

You must use a certificate provider who provides DNS validation.

Use a Certification Authority Authorisation (CAA) record on your service.gov.uk domain. This stops attackers from getting another certificate authority to issue a certificate for the domain.

If you need to use extended validation for your service, your organisation will need to act as the legal confirming party. This can be a very lengthy process.

Sending emails from your domain name

If you鈥檙e planning to send emails from your domain name, you must make sure your users can receive your emails and are protected from spam.

You must follow the government guidance on how to email your users.

If you鈥檙e not going to send emails from your domain, you must follow the government guidance on keeping your domain protected from spoofing attacks.

Getting operations support

If you have an issue you cannot resolve with your DNS supplier, you can email the 188体育 operations support team at [email protected]. The team is available on weekdays between 9am and 5pm.

If you have an emergency outside of these hours, you must contact your organisation鈥檚 single point of contact (often referred to as 鈥楽POC鈥�) who will contact the support team for you.
