About this network

AS50309 is operated by Arcadiz Telecom NV.

What it's used for

• The address space carries a mix of Arcadiz-owned blocks (netnames BE-ARCADIZ1-) and space registered to third parties, including Emmaus vzw, group S - Sociaal Secretariaat vzw, and SerSo BVBA.
• With 6,144 IPv4 addresses announced across 7 prefixes and 135 observed neighbours, the high neighbour-to-address ratio indicates a transit or upstream provider role rather than a large-scale access network.
• As a Belgian telecom operator, traffic from this AS includes business connectivity, VoIP services, and transit for smaller Belgian networks and organizations.

Notable

• Registrants for the majority of prefixes match the announcer, specifically Arcadiz Telecom NV, while three prefixes are registered to distinct Belgian entities.
• The address inventory is fragmented across multiple /22 and smaller blocks, with one /21 being the largest single allocation.
