Summary
Illinois Rural Telecommunication Co.
rural telecom residential wireless
The AS handle IRTC-NET is held by Illinois Rural Telecommunication Co.
What it's used for
- The address space carries residential and wireless access traffic, evidenced by reverse DNS names such as
subs-192.196-228-0.irtc.net,radio-66-51-185-0.irtc.net, andsub-68-69-33-0.irtc.net. - The network announces 13,568 IPv4 addresses across 20 prefixes and 1 IPv6 prefix, while maintaining only 2 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.
Notable
- Registrants for the majority of prefixes are consistent with the announcer, listing "Illinois Rural Telecommunication Co." and "Illinois Rural Telecommunications," though the 216.8.76.0/23 block is registered to "Hanson Information Systems, Inc. / Family Net" under the netname
HISNET. - The inventory consists of a large /20 block alongside numerous /22, /23, and /24 prefixes, reflecting a finely subdivided corporate estate typical of rural telecom operators managing site-by-site segmentation.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
