Increase trust with SSL

Why is SSL important?

An SSL certificate ensures all information transmitted to and from your website is protected from third parties attempting to access it. It is important because browsers, like Google Chrome, mark pages without https and the green padlock in the address bar as not secure. This can have a negative effect on the trustworthiness of your website. Pages that are protected with SSL receive better search engine rankings and are more likely to be trusted by visitors.

What is Wildcard SSL?

With IONOS, your domain comes with one free Wildcard SSL certificate per contract. While a standard SSL certificate only protects one domain, a Wildcard SSL certificate protects the domain name, as well as all related subdomains, like

Buy domain names – FAQ

Every website has a specific name to identify it on the web, called a domain name. Like your home address, it consists of different parts. The domain name has to be unique and only lead to one website. That’s why you need to check if the domain name you want is still free and not already taken.

A domain name may start with “www.” but web browsers will recognise it automatically, so it’s not essential. The next part of the domain name, the second-level domain, is what people will recognise and remember. It could be your company’s name, for example. The last part is the top-level domain (TLD), which can be generic (.net, .com, .org) or geographic like .uk or .cymru.

To find out if the domain name you want to register is available, use the IONOS domain checker.

Finding the right domain name is the first step in building a successful website and boosting your online presence. Without a strong domain, you risk getting lost in the crowd.

Decide early on if you want to have a brand domain or a keyword domain. Brand domains make a clear link between your business and your website, whereas keyword domains may get better search engine results.

Classic domain extensions like .com work for both options. Country specific extensions (e.g. emphasise local relevance, and new top-level domains (nTLDs "") such as .video, .business etc. can also be effective.

It's worth registering more than one domain extension, especially the classic extensions such as .com, as many users will remember them better than the nTLDs. If you own the .com version but prefer the nTLD, you can always set up domain forwarding. This also prevents someone else from using your domain name.

It's easy to register a domain name. Here's our step-by-step guide.

  1. Choose the domain name you want for your website. You can register more than one.
  2. Check whether your domain name is available using our domain checker tool. This will tell you if the domain contains invalid characters, or if it's already claimed.
  3. If your preferred domain name is taken, you'll be given alternatives.
  4. Add your chosen domain/s to your basket. There may be several different package options to choose from depending on your needs.
  5. Check your order for details such as the domain's expiration date, and how many domains you're registering.
  6. Create your customer account if you don't already have one.
  7. Select your payment method and purchase your domain/s.

If you're already an IONOS customer, you can add new domains by logging in to your account and clicking "add new domain" in the domains drop-down menu.

A domain extension is also known as a top-level domain (TLD). It's the last part of a domain name – in the domain name, .com is the domain extension. In an already crowded marketplace, it can be a challenge to choose a memorable and unique domain name, and this includes picking the right domain extension.

There are different kinds of domain extension:

ccTLDs are top-level domains that represent a nation – the 'cc' stands for country code. Some of these domain extensions can require a presence in the relevant country. A or .uk domain are examples of ccTLDs. Some of the country code extensions are classified as generic ccTLDs by Google – gccTLDs. This is because the domain is not always used to represent a country. For instance .cc and .io are generic country code top-level domains. The .cc extension is officially the country code extension for the Cocos (Keeling ".io") Islands near Australia, but is also used as 'commercial company', while .IO is the ccTLD for the British Indian Ocean Territory, but is also used to represent 'input/output'.

gTLD is short for generic top-level domain. The classic domains .com, .org, .net are generic domain extensions.

nTLDs are new top-level domains. Each year, up to 1,000 nTLDs are released. They include extensions such as .london, .rugby and .tech, .cloud.

Certain domain extensions have eligibility requirements, for example the extension .gov is restricted to use by government entities. IONOS does not offer these domain extensions.

Subdomains are useful for organising your website into different categories. Possible categories include:

Geographical areas or language groups

For example, if your website is in English and Spanish, a subdomain may be used to indicate that this section of your website will be in Spanish, and not English – so instead of just, would be used.

Product-oriented sections

If your website offers a variety of different services or products, you can create a subdomain for each one, for example

Gated content

Having a separate subdomain for logins or account pages on your website is a useful way of organising your site.

By using a subdomain, you'll be able to track the success of your website more accurately, as you'll see how different sections are performing.

Every domain name is linked to an address on the internet called an IP address, which is a long string of numbers. Domain names make it possible for internet users to visit websites without having to remember this numerical address. When you visit, your browser and computer reads our site's DNS records in order to locate our website's files which are stored on a server. This almost instantaneous directing process allows your browser to access and load websites.

Like IONOS, most hosting providers automatically assign DNS records upon domain name registration. In some cases, you may wish to keep your registered domain with one company, but have your website's files and email accounts stored on a different hosting server.

This is called a DNS transfer, and can be arranged within a couple of days. You may want to alter your DNS records if your domain registration was completed with an expensive hosting company. In this case, you can keep your registered domain but switch to a more affordable hosting provider such as IONOS.
