Adressområde

Adressområde is a term used in Danish, Norwegian and related contexts to describe a defined geographic area associated with a group of addresses. The concept is used in administration, planning and service delivery to organize and manage tasks tied to locations.

In urban planning and municipal administration, an adressområde groups together streets and properties to support property taxation, zoning, infrastructure planning, and public services such as waste collection or emergency response. Boundaries are typically derived from cadastral data, street networks, or administrative divisions and can be adjusted as areas evolve.

In postal and address management, an adressområde often corresponds to a district, postal code area, or delivery zone. Defining such areas helps optimize mail routing, address verification, and service coverage. The exact size and borders of an adressområde vary by country, region, or service provider.

In computing and networking, address range (adressområde) refers to a contiguous set of addresses defined by a starting and ending value. It is used for access control, routing, subnetting, or memory management. Examples include IPv4 ranges such as 192.168.0.0 to 192.168.255.255 or memory ranges like 0x00000000 to 0x0FFFFFFF. CIDR notation (for example 192.168.0.0/16) expresses ranges compactly.

Defining rules for adressområder involves governance and data sources: geographic areas rely on government or utilities and may update with changes in population or infrastructure, while technical ranges are established by network or software administrators and enforced by devices and policies.
