Summary

isp telecom business
Two spellings of the same generated hostname, differing by one hyphen, inside a single block.
What it's used for
- A German regional internet provider. 175,872 addresses across 11 IPv4 prefixes, seven IPv6 prefixes, and 121 observed BGP neighbours.
Notable
- Seven of 18 sampled addresses returned names, in two forms that differ by a single character:
a-89-182-128-0.net-htp.deanda89-182-255-255.net-htp.de. - Both forms appear inside the same
89.182.0.0/15. - Own netnames run
DE-HTN-990315,DE-HTN-20020801,DE-HTN-20060406andDE-HTN-20150325. - Three blocks belong to other organisations, including one to the city of Hannover, netname
LHHTEKI-LAN.
Interesting
- One hyphen separating the leading letter from the address in some names and not others is a generator that was rewritten and never applied backwards over the space it had already filled. The two forms resolve equally well, so nothing forces the fix, and the boundary between them marks where the change happened.
- A city government's local network sitting under a regional provider's AS number is the municipal utility model: the same company that runs the town's other services also runs its connectivity, and the registry keeps the two holders separate.
990315and20150325again show the six-digit and eight-digit date forms in one holder's records, sixteen years apart.

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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
