A domain name is the address for a website that appears in the browser bar. For example, our domain name is '123 Reg.co.uk'. There are two parts to every domain: the main name (i.e. '123 Reg') and the extension (i.e. '.co.uk'). No two websites can have the same domain name because it is unique to you.

You can check the availability of a domain name by using the search function displayed on this page or on our Homepage. Simply enter your ideal name and you’ll be given a list of relevant options for you to purchase. If your ideal web address has already been taken, then you can use our backordering service to secure it as soon as it becomes available.

Every site is hosted on an internet web server, or a “host”. Computers access these hosts using an IP – a string of numbers like 92.51.159.41 – but that’s not very memorable for human beings. A Domain Name converts an IP address to a more memorable, text-based version so that people don’t need to punch in a huge string of numbers to find the websites they want. This is all done through the Domain Name System – more commonly known as DNS. Think of your domains like web addresses – the place people will find you online.

An extension is the ending of a Domain Name. Extensions are commonly referred to as a TLD (Top-Level Domain), suffix, or domain root. There are many types of TLDs such as ccTLDs, which are country code specific, like .uk for the UK, and gTLDs, which are new generic extensions such as .website. Some of the most popular TLDs include .com, .org, .net and .biz. Many businesses and brands register their name with multiple extensions to protect their online identity, increase visibility and attract more visitors to their website. Some of the most popular extension types are Geographic and International domains. Geographic TLDs are perfect for local businesses and organisations. They tell people in which city or region a shop, a restaurant or an agency is located. Extensions like .london, .vegas, .berlin and .tokyo are a great choice for attracting local customers. International TLDs are the ideal choice for brands looking to promote their local presence and connect with customers from a specific country. Depending on which market or country you wish to target, you can go with an established international extension like .de, .es, .it or with the new .uk or .global.

gTLD stands for generic Top-Level Domain. It’s a category of extensions that are alternatives to the traditional .com, .co.uk and .de suffixes. Also called ‘new gTLDs’ or ‘nTLDs’, these are just a few of the hundreds of new names to search for that have been released recently for businesses and individuals to use. These gTLDs vary from practical extensions such as .web or .tech, to location-based ones such as .london or .wales, and even catchy extensions such as .ninja or .xyz. Find out more about gTLDs and check if yours is available now.

Country-code Top-Level Domains (ccTLDs) correspond to a country, territory, or other geographic location. For example: .uk represents the United Kingdom, .de is for Germany, .mx for Mexico and .ch is used for Switzerland. The rules for registering ccTLDs vary significantly depending on the extension. Some ccTLDs such as .de have residency restrictions, meaning that registrants are required to be located in the country of the domain extension they want to use. However, many of the ccTLDs can be registered by anyone without any restrictions, including .uk, .ch, .es and several more.
