Summary
inexio / Deutsche Glasfaser
isp legacy
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.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
