klientadresse

Klientadresse is a compound term used in several Germanic languages to denote the address associated with a client. Its meaning depends on context: in information technology, it usually refers to the network address of a client device; in business and CRM contexts, it can refer to the client’s postal or billing address.

In computing and networks, the klien­tadresse is the identifier that locates a client within a network. The most common form is the IP address (IPv4 or IPv6), used to route data packets to and from the client. The client address is typically logged by servers for access control, analytics, and troubleshooting. When clients are behind intermediate devices such as NAT gateways or proxies, the actual originating address may be hidden behind a forwarded or reconstructed header (for example, X-Forwarded-For), which requires careful handling for security and privacy.

In software design, the client address can influence authentication, session management, and rate limiting. Applications may rely on the client address to apply rules, tailor responses, or enforce geographic restrictions. Privacy concerns arise because IP addresses can reveal information about a user’s location and activity; many jurisdictions regulate the processing and retention of such data.

In business contexts, klientadresse can denote the client’s physical or mailing address used for correspondence, invoicing, or shipping. This usage is distinct from the technical sense and appears in contracts, invoices, and customer records.
