IPv4 (Internet Protocol Version 4) is a 32-bit addressing system that provides unique numerical identifiers for devices on a network. With IPv4 address exhaustion, a secondary resale market has emerged, where organizations buy and sell unused addresses to meet ongoing demand, while IPv6 adoption gradually replaces IPv4 for scalability.

Brander Group is a qualified brokerage firm to buy and sell IPv4 addresses in the ARIN, APNIC, and RIPE NCC regions
