About this network

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, and sub-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.
