What this means These dates come from the registry's RDAP record (source: rdap.nominet.uk). "Registered" is when the current registration began — if a domain lapsed and was registered again, the clock restarts. We never show personal registrant details. See what domain age means.

Open the Wayback Machine calendar

What this means The Internet Archive's Wayback Machine saves copies of web pages. The first capture shows roughly when a site first appeared on the web — it can be later than registration (nothing published yet) or earlier (an older owner). See the Wayback Machine guide.

Popularity and traffic

In the Tranco list
Tranco rank
Information #1,982 of the top million (listed as www.nhs.uk)
Tranco rank 1,982 on a logarithmic scale#11k1m
Traffic (rough estimate)
Information 500,000 – 50 million visits a monthA deliberately wide band based only on the rank band (top 10,000). Not measured.

Rank from the Tranco list (list ID Y83KG, 4 Oct 2026), a research ranking by Le Pochat et al. that averages several popularity sources over 30 days.

What this means A rank shows how popular a site is compared with others — 1 is the most popular. Turning a rank into visitor numbers is guesswork, so we show a very wide band and explain the method on our methodology page.

Estimated worth

Rough estimate

£5,000 – £25,00065 points

For interest only — not a valuation. A domain is worth what a buyer will pay; this simple formula can't see trademarks, backlinks, sales history or demand.

IPv6
Worth a look No IPv6 address for the domain or www
DNSSEC validation
Information Not validated (unsigned, or not checked)

What this means DNS records tell the internet where a domain's website and email live. SPF lists the servers allowed to send its email and DMARC tells receivers what to do with messages that fail checks — both help stop spoofing. DKIM keys live under selectors we cannot guess, so they are not shown. Read DNS records explained and SPF, DKIM and DMARC.

Reverse DNS

CDN / platform hint
Azure Front Door

What this means The hosting network is the autonomous system (AS) that announces the website's IP address on the internet — often a hosting company or a content delivery network (CDN). Looked up through Team Cymru's IP-to-ASN service.

The name itself

Name facts

nhs 3 characters
Whole domain
nhs.uk 6 characters
Characters
Good 3 letters, 0 digits, 0 hyphens
Internationalised (IDN)
No — plain ASCII
Dictionary
Not a dictionary word (or not one in our list)
Pronounceable
Not by our simple test
Ending
.uk A country-code ending

What this means Short, easy-to-say names without hyphens or digits are easier to remember and type. Domain names can be up to 63 characters per label; in DNS, non-ASCII names are stored as "xn--" Punycode.

Good Found (a sitemap index)

What this means We load the home page once over HTTPS and once over plain HTTP, following up to five redirects, and read only the page's headers and head tags — we don't store the page. A missing title or description is worth fixing for search results; a robots "noindex" keeps a page out of search engines.

Connection
TLSv1.3 TLS_AES_256_GCM_SHA384

What this means A TLS certificate proves the server is entitled to use the name and encrypts the connection. Certificates now last months rather than years, so automatic renewal matters. Read SSL certificates explained.

Security headers

Partly protected

4/6 recommended security headers present on the home page.

Strict-Transport-Security (HSTS)
Good Set — remembered for 730 daysTells browsers to use HTTPS only.
Content-Security-Policy
Worth a look Not setLimits where scripts and other content can load from.
X-Content-Type-Options
Good nosniffStops browsers guessing file types.
Frame protection
Good SetX-Frame-Options or CSP frame-ancestors — prevents clickjacking.
Referrer-Policy
Good SetControls what address is passed on when visitors click away.
Permissions-Policy
Information Not setTurns off browser features the site doesn't use.

What this means These response headers are defences a site can switch on in its server settings. Missing ones are common and not proof of a problem, but they are cheap to add.
