Summary

South Slope Cooperative Telephone Company

United States of America · AI-generated

residential cooperative iowa isp

The AS handle SSTC-NET-1 is held by South Slope Cooperative Telephone Company.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as dyn-66-129-207-255.dyn.southslope.net and 0.58.49.198.sta.southslope.net.
  • The network announces 35,840 IPv4 addresses across 38 prefixes and 1 IPv6 prefix, while maintaining only 4 observed neighbours, a ratio indicative of an access network rather than a transit provider.

Notable

  • Registrants for the majority of prefixes align with the announcer, including South Slope Cooperative Telephone Company and South Slope Network Operations Center, though some blocks are registered to Aureon Network Services.
  • The address inventory is fragmented into numerous small /23 and /24 blocks alongside larger /19 and /20 allocations, reflecting a long history of incremental growth and acquisitions.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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 1,779 prefixes, as published 2026-10-23. 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.
