Explore useful UK articles about DNS, with practical explanations and next steps for your website.
Domain namesUK domains use standard DNS records within the UK naming hierarchy. Follow the lookup process, identify the authoritative source and understand how website records, email, caching and DNSSEC fit together before changing a live .uk or .co.uk service.
Domain namesDNS propagation is the usual name for the period when different users can receive different DNS answers after a change. It happens largely because resolvers and devices cache earlier information. The updated record is not pushed instantly to every computer that might use the domain.
Domain namesDNS can delay a first connection, but not every slow page has a DNS problem. Learn a repeatable testing method, understand cache and resolver effects, and prioritise authoritative reliability, hosting, images and third-party services using actual evidence.
Domain namesA failing website does not always mean DNS is broken. Work through fourteen common problems with a practical diagnosis-first approach, separating address records, delegation, caching, DNSSEC, email authentication and application errors so each change has a clear purpose.
Domain namesCNAME records connect one hostname to another, but they do not redirect a browser or move a URL path. Understand practical uses for branded subdomains, apex restrictions, service verification and a careful setup process that avoids loops and conflicting records.
Domain namesDNS works quietly whenever someone visits your website or sends your business an email. This beginner’s guide explains resolvers, nameservers, caching and domain changes using practical examples, then shows how to separate a DNS fault from a hosting problem.
Domain namesYour website, business email and connected services depend on different DNS records. Learn what A, AAAA, CNAME, MX, TXT and NS records actually do, how to recognise the right values, and how to change them without disrupting unrelated services.
Domain namesDNS records connect a domain to the services behind it. Use this practical reference to understand the main record types, read the name and value fields correctly, and distinguish website destinations, mail routing, verification and nameserver delegation.
Domain namesDNS turns a familiar hostname into information your device can use to connect to a service. Follow a complete uncached lookup step by step, see where cached answers shorten the process, and learn how to distinguish a DNS failure from a website problem.
Domain namesDNS is a business dependency that often becomes visible only when it fails. Learn how resolvers, authoritative servers and caching affect your website and email, and how to manage the domain, provider and change processes that keep services reachable.
Domain namesPointing a domain at a host can mean changing website records or moving the whole DNS service. This guide helps you choose the appropriate method, prepare the hosting account, preserve email and test the result from DNS through to the live website.
Domain namesNominet runs the .uk registry, while your registrar usually handles everyday domain management. This guide explains the difference, the policies and infrastructure behind your address, and the practical responsibilities that remain with the person or organisation registering it.
