Know what you are choosing
Generic TLD, country-code TLD or registration suffix?
The distinction matters when you compare policies, eligibility and registrar support. A complete domain can use more than one label to the left of the actual top-level domain.
Country-code extension
A two-letter top-level domain associated with a country or territory.
Registration suffix
A structured ending beneath a TLD where registrants commonly obtain names.

Extension questions
Understand the namespace before choosing the name
The final registrar and registry remain the source for live price, policy and availability information.
What is a top-level domain or TLD?
A top-level domain is the final label in a domain name, such as com, org or uk. People often use “TLD” more loosely for a registration suffix such as co.uk, so this directory clearly distinguishes the two.
Is co.uk a TLD?
The TLD is uk. The co.uk ending is a second-level registration suffix within the .uk namespace. Registrants commonly buy names directly beneath co.uk, which is why it remains useful to search and compare as a complete suffix.
Does the extension affect the value of a domain?
It can influence recognition, audience fit, availability and buyer demand, but it is only one part of value. The words, memorability, history, comparable sales, restrictions and intended use all matter.
Are country-code domains only for local businesses?
Not always. Policies differ by registry: some have eligibility or local-presence rules, while others are used more broadly. Confirm the current requirements for the exact suffix before committing to a name.
Why do prices differ so much between extensions?
Registries set different wholesale structures and premium-name policies, while registrars add their own promotions, services and margins. Always compare registration, renewal, transfer and restore costs in the same currency.
Can DHG check every extension shown here?
Extension information and DHG availability-checking support are separate datasets. Use the current software and member documentation to confirm which suffixes are supported by a particular DHG workflow.
