Summary

Mahaska Communication Group

United States of America · AI-generated

fiber residential iowa isp

The AS handle MCG-NET-1 is held by Mahaska Communication Group, LLC.

What it's used for

  • The space carries residential fiber internet services, evidenced by reverse DNS entries like fd4-18-254.mahaska.org and netnames such as MAHASKA-COMM-GRP-CGNT-NET-1.
  • With 16,128 IPv4 addresses announced across 20 prefixes and only 1 observed neighbour, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants largely align with the announcer, including Mahaska Communication Group and Mahaska Communication Group, LLC, though some prefixes are registered to Cogent Communications, LLC and Aureon Network Services.
  • The address inventory is a mix of /20, /21, /22, /23, and /24 blocks, with the largest being 38.128.208.0/20.
  • The operator is a local fiber internet provider serving communities in Iowa, distinct from the unrelated Mahaska Bottling Company.

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: 453 networks and 1,848 prefixes, as published 2026-11-12. 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.
