navneopppløsning

Navneoppløsning, often translated as name resolution, is the process of translating a human-readable name into a machine-readable identifier. In the context of computer networks, this most commonly refers to the translation of domain names into IP addresses. When a user types a website address like www.example.com into their web browser, their computer needs to know the corresponding IP address (e.g., 192.168.1.1) to connect to the web server hosting that website.

The primary system responsible for this type of navneoppløsning on the internet is the Domain Name System (DNS). DNS acts as a distributed database that maps domain names to IP addresses. When a navneoppløsning request is made, it typically involves a series of queries to DNS servers. Initially, the user's computer might check its local cache for the IP address. If not found, it queries a local DNS resolver, which in turn may query other DNS servers, including authoritative name servers for the specific domain, until the IP address is found.

Beyond domain names and IP addresses, navneoppløsning can also refer to other translation processes. For instance, in some operating systems, it might involve resolving network service names to port numbers or even resolving user account names to unique security identifiers. The fundamental principle remains the same: converting a more abstract, human-friendly representation into a concrete, machine-usable identifier necessary for various system operations.
