About this network

EICAT is the autonomous system for E. I. Catalyst, a regional cable and DSL internet service provider in Canada.

What it's used for

• The address space carries residential and business access traffic, evidenced by reverse DNS entries such as H255.C23.B96.mbs-bb.eicat.ca and H0.C68.B0.tor.eicat.ca, which indicate host-based naming conventions typical of subscriber networks.
• The AS announces 8,448 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 10 observed neighbours; this ratio of significant address inventory to a moderate peer count is consistent with an access network distributing connectivity to end-users rather than providing transit.

Notable

• Registrants for the two largest prefixes, 66.96.16.0/20 and 72.0.64.0/20, are listed as E. I. Catalyst, aligning with the AS holder, while the smaller 205.189.139.0/24 prefix is registered to SCINet Communications under the netname NET-SCINET.
• The address inventory consists of two large /20 blocks and one /24 block, with the /24 representing a distinct segment likely associated with the SCINet registration.
