About this network

DEUTSCHE-GLASFASER is held by inexio Informationstechnologie und Telekommunikation GmbH, the Saarlouis-based regional carrier that merged with Deutsche Glasfaser in 2020. The combined group is one of Germany's larger fibre-to-the-home builders.

What it's used for

• Carrier and access networking for the group: broadband access lines plus upstream transit for Deutsche Glasfaser Wholesale (AS60294), which carries much of the group's FTTH customer pool.
• Sampled rDNS is the generic per-address form German access networks use: 001-032-234-077.ip-addr.inexio.net — the four octets reversed into the label, applied uniformly across the block. That is end-user access naming, not named servers.

Notable

• Small for its role: about 7.4k IPv4 addresses across 11 prefixes, but roughly 118 observed BGP neighbours. The peering footprint, not the address count, is the size signal here — this AS behaves as the group's carrier edge.
• Most of its space sits in 94.31.64.0–94.31.120.0, directly adjacent to the blocks AS60294 uses for dynamic FTTH pools.

Interesting

• inexio grew out of rural Saarland and Rhineland-Palatinate build-outs, areas the national incumbent had largely skipped, which is why a legacy AS from 2000 still fronts a network whose retail brand is now Deutsche Glasfaser.
