Addrex, Inc. operates in the technology, information, and internet sector with a focus on the secondary market for IPv4 number assets. The company positions itself as a neutral facilitator in a double-blind marketplace that connects qualified sellers with a broad base of vetted buyers, leveraging standardized legal agreements and escrow services to support secure transactions. Its primary offering, the Addrex Marketplace, enables around-the-clock online trading of IPv4 blocks, aiming to provide a safe and efficient channel for participants to complete transfers. Headquartered in Herndon, Virginia, Addrex was founded in 2009 to foster this niche market and has its origins tied to brokering the first legal sale of IPv4 number blocks in a 2011 Microsoft–Nortel deal. The marketplace serves organizations seeking IPv4 assets and those looking to sell, with a focus on protecting buyer and seller identities through the closing process. The company operates within the broader technology, information, and internet industry and maintains a global reach through its online platform.
