Understanding Domains and DNS
This page provides information about Scaleway’s Domains and DNS service.
A domain name is an identification string that defines a realm of administrative autonomy, authority, or control within the Internet. Domain names are formed by the rules and procedures of the Domain Name System (DNS). Any name registered in the DNS is a domain name.
Domains are further divided into subdomains, that become DNS zones with their own set of administrators and DNS servers.
The term domain is used in the business functions of the entity assigned to it and the term zone is usually used for configuration of DNS services.
domain_example.com is the
domain and has only one owner who can manage it.
By default, the domain only has a root zone and no subdomains.
example.com allows you to configure records such as:
example.com├── (root)├── www # www.example.com├── mail # mail.example.com└── www.dev # www.dev.example.com
If we add a DNS zone to the subdomain
dev.example.com, we get:
example.com├── (root)│ ├── www # www.example.com│ └── mail # mail.example.com│├── dev└── www # www.dev.example.com
Multiple zones (i.e. subdomains) allow:
- access delegation to zone(s) (preventing access to the root zone)
- access (future) to features based on
- performance tuning. For example if you have 10 000 records, we recommend that you divide them into x zones or subdomains.
- To be RFC compliant, each zone will automatically have name server records added.
An internationalized domain name (IDN) is an Internet domain name that contains at least one label that is displayed in software applications. The label is in whole or in part in a language-specific script or alphabet, such as Arabic, Chinese, Cyrillic, Tamil, Hebrew, or the Latin alphabet-based characters with diacritics or ligatures, such as French. These writing systems are encoded by computers in multibyte Unicode. Internationalized domain names are stored in the Domain Name System as ASCII strings using Punycode transcription.
