Summary

Ritter Communications

United States of America · AI-generated

residential isp cable business

RITTERNET-MIL is the autonomous system for Ritter Communications, a regional telecommunications provider.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as dsl178128.bigriver.net and host126-179-178-64.bigriver.net.
  • The AS announces 4096 IPv4 addresses across 11 prefixes with only 1 observed neighbour, a ratio that indicates an access or eyeball network rather than a transit provider.

Notable

  • All registrants in the RDAP data are listed as Ritter Communications, consistent with the AS holder.
  • The netnames BIGRIVER-INTERNET and RITT appear across the inventory, with the former dominating the larger blocks.
  • The inventory consists of 11 IPv4 prefixes with no IPv6 prefixes announced.

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 1,784 prefixes, as published 2026-10-19. 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.
