Summary

Ben Lomand Connect

United States of America · AI-generated

rural isp residential cooperative

The AS handle BEN-LOMAND-TEL is held by Ben Lomand Rural Telephone Cooperative, Inc.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as calx-254.dhcp.g4-r2.tnspnc.benlomand.net which indicate DHCP-assigned customer endpoints.
  • The network announces 74,752 IPv4 addresses across 30 prefixes and 13 IPv6 prefixes, maintaining 19 observed neighbours; this ratio of substantial address inventory to a moderate peer count is characteristic of a regional access provider.

Notable

  • All sampled registrants align with the announcer, consistently listing Ben Lomand Rural Telephone Cooperative, Inc. with netnames like BLC-152-97-64-0 and BLTC-2.
  • The address inventory is finely subdivided into numerous /20, /21, and /22 blocks, reflecting site-by-site segmentation typical of a rural cooperative managing distributed infrastructure.

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.
