One netname names a village and a carrier interconnect; the other has an underscore in it.
What it's used for
- A regional provider. Two IPv4 prefixes announced from Germany, no IPv6, seven hundred and sixty-eight addresses, through one observed BGP neighbour.
Notable
- The first netname combines the company, two letters, an abbreviation for a network-to-network interface, and the name of a small town, so it records exactly where one interconnect lands.
- The second is the company name twice in mixed case joined by an underscore, a character the convention for these fields does not usually admit.
- Neither registrant field names an organisation. Both list only a role for abuse.
- All three answering addresses give the four octets fully reversed and padded to three digits each, under a subdomain that is an abbreviation for the words internet protocol address.
- Six addresses were queried for reverse DNS and three returned a name.
Interesting
- Naming a village in a netname is more precise than most operators are willing to be. It says which building the circuit terminates in, to anyone who reads the field.
- Reversing and padding the octets makes every name the same length, which sorts and aligns neatly in logs. It also makes the name unreadable to a person at a glance.
- The AS handle names a whole region while the netname names one town, so the ambition and the current footprint sit side by side in the same record.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-07, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
