Summary

NbIServ

Germany · AI-generated

isp residential germany small

NBISERV-AS is operated by Martin Prager trading as "NbIServ".

What it's used for

  • The address space carries residential and small-business internet access, evidenced by the reverse DNS record 254-18-182-46.nbiserv.com and netnames such as DE-NBISERV-20101119 and DE-NBISERV-20110316.
  • The AS announces 3072 IPv4 addresses across 6 prefixes and 5 IPv6 prefixes, with only 2 observed routing neighbours. This high address-to-neighbour ratio indicates an access network providing last-mile connectivity rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and small business endpoints located in Germany, consistent with the operator's role as a regional Internet Service Provider (NSP) serving the Bethenhausen area.

Notable

  • Registrants for the majority of prefixes align with the AS holder, listing "Martin Prager trading as 'NbIServ'" for 46.182.16.0/22, 31.185.110.0/23, 46.182.20.0/23, 31.185.104.0/24, and 46.182.23.0/24.
  • The prefix 45.149.216.0/23 is registered to Daniel Schneider under the netname DE-SYNO-CLOUD-20190905, indicating a distinct registration within the announced space.
  • The inventory includes a mix of /22, /23, and /24 IPv4 blocks alongside large /32 and /31 IPv6 allocations, reflecting a typical small ISP address estate.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
