    Hunting Routing Resources around the World

    Following the progressive exhaustion of IPv4 address space, we observed a parallel growth in commercial trading of available IPv4 addresses which led to a global redistribution of address blocks from their original “birthplace”. Such is the case of address blocks that had been originally allocated by a given Regional Internet Registry (RIR) – say ARIN, for example – but were then sold to a company that started to use and announce them in a completely different region – say RIPE. While this is perfectly fine and legitimate, it sometimes poses an additional burden on those subjects, namely Internet Exchange Points, that rely on information stored into Internet Routing Registries (IRR)…

    “Switching” to IP fabrics

    At the beginning of 2021, Namex IXP has started the rollout of its next-generation peering platform, the active infrastructure which is at the core of its network interconnection facility. This new platform relies on an IP fabric design with VXLAN as the overlay network and BGP EVPN as the control plane protocol. The development of this project started back in March 2020 and saw Mellanox and Cumulus Networks (both parts of NVIDIA corporation now) as major technological partners. Before diving into the details, a brief historical note may help to understand the drivers and motivations behind such technical choices. Managing scale and complexity: the evolution of a peering platform Having…
