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
- #10,905 of the top million
- Traffic (rough estimate)
- 50,000 – 5 million visits a monthA deliberately wide band based only on the rank band (top 100,000). 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.

- IPv6
- No IPv6 address for the domain or www
- DNSSEC validation
- 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.
Hosting network

- AMAZON-02 - Amazon.com, Inc., US
- AS number

- IP block

- Reverse DNS

- CDN / platform hint
- Amazon CloudFront
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.
Search engines
Not checked automaticallyWe don't check Google or Bing automatically: neither offers a free API for this, and we don't scrape search results. You can check yourself with a site: search:
- Common Crawl
- Found in the September 2026 IndexCommon Crawl is an open, free web archive — a rough sign of whether crawlers reach the site. Sites can block its crawler (CCBot) in robots.txt.
What this means A site: search shows a sample of the pages a search engine has indexed — the count is only an estimate. For a definite answer for your own site, use Google Search Console and Bing Webmaster Tools. See how to check Google indexing.
The name itself
Name facts- Name part
- which 5 characters
- Whole domain
- which.co.uk 11 characters
- Characters
- 5 letters, 0 digits, 0 hyphens
- Internationalised (IDN)
- No — plain ASCII
- Dictionary
- "which" is a dictionary word
- Pronounceable
- Not by our simple test
- Ending
- .co.uk A second-level ending under a country code (like .co.uk)
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.
Website
Website loads- Status
- 200 OK
- Final address
- https://www.which.co.uk/ Visit site

- Loads over HTTPS
- HTTP → HTTPS
- Plain HTTP redirects to HTTPS

- Open Graph tags
- Present (7 tags) — links shared on social media get a title and preview
- robots.txt
- Found · lists 1 sitemap
- sitemap.xml
- 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.
SSL certificate

- www.which.co.uk

- Yes — the chain verifies against standard root certificates

- whichbestbuys.com
- whichlegalservice.co.uk
- whichswitch.com
- whichswitch.co.uk
- Connection
- TLSv1.3 TLS_AES_128_GCM_SHA256
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 protected4/6 recommended security headers present on the home page.
- Strict-Transport-Security (HSTS)
- Set — remembered for 365 daysTells browsers to use HTTPS only.
- Content-Security-Policy
- Not setLimits where scripts and other content can load from.
- X-Content-Type-Options
- nosniffStops browsers guessing file types.
- Frame protection
- SetX-Frame-Options or CSP frame-ancestors — prevents clickjacking.
- Referrer-Policy
- SetControls what address is passed on when visitors click away.
- Permissions-Policy
- 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.
Other endings

- which.uk Registered since 2014
- which.net Registered since 1996
- which.org Registered since 2000
- which.info Apparently available Check at NameSilo
What this means "Apparently available" means the registry's RDAP service has no record of the name. Some names are reserved or premium-priced, so confirm at a registrar before relying on it.
