Summary

LUMi GmbH

Germany · AI-generated

isp residential cable dsl

INC is operated by LUMi GmbH, a German telecommunications provider.

What it's used for

  • The address space carries residential and business internet access, evidenced by netnames such as DE-INGENIA-20190215 (ingenia digitale Netze GmbH & Co. KG), DE-JOBST-DSL-20160406 (JOBST NET GmbH), and DE-SWPSTADTWERKE-20051123 (SWP Stadtwerke Pforzheim GmbH & Co. KG).
  • With 11,776 IPv4 addresses announced across 16 prefixes and only 2 observed neighbours, the network functions as an access provider rather than a transit carrier.
  • Reverse DNS entries like isp.dynamic.ingenia-digital.de and dynamic.as39257.net confirm the space serves end-user connections, including dynamic and static residential IPs.

Notable

  • Registrants include LUMi GmbH, Interactive Network Communications GmbH, ingenia digitale Netze GmbH & Co. KG, JOBST NET GmbH, SWP Stadtwerke Pforzheim GmbH & Co. KG, and Stadtwerke Unna GmbH, indicating a portfolio of acquired or partnered regional ISPs.
  • The inventory is finely subdivided into multiple /22 and /24 blocks, reflecting the integration of distinct regional networks under a single AS.

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: 443 networks and 1,779 prefixes, as published 2026-10-25. 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.
