The domain, often referred to as the web address or Internet address, is the unique and identifiable address of a website on the Internet. It enables users to access a specific website without having to enter the complex numerical IP address. In essence, the domain acts as a memorable name that is resolved in the Domain Name System (DNS) to one or more specific IP addresses. Each domain name is unique worldwide and is managed by a hierarchical system of registries and registrars.
Components of a domain
A domain is made up of several hierarchically organized components:
- Top-level domain (TLD): This is the last part of the domain name after the last dot. A distinction is made between generic TLDs (gTLDs) such as
.com,.orgor.netand country-code TLDs (ccTLDs) such as.defor Germany or.chfor Switzerland. Since 2013, there have also been new gTLDs such as.storeor.berlin. - Second-level domain (SLD): This is the individual name that an operator chooses for their website. It is placed directly in front of the TLD, for example „agenturxy“ in
agencyxy.com. The combination of SLD and TLD forms the actual domain name that a user registers. - Subdomain: Optionally, subdomains can be placed in front of the SLD to identify specific areas or services of a website, for example
blog.agenturxy.deorstore.agenturxy.de. The subdomain is technically a part of the main domain and extends its structure.
