Summary
South Arkansas Telephone Company
isp legacy
SOUTH-TELEP is South Arkansas Telephone Company (SATCO), a small rural incumbent telephone company based in Hampton, Arkansas.
What it's used for
- Rural broadband and telephone service in south-central Arkansas, serving communities including Hampton, Harrell, Banks, Hermitage and Louann.
- Reverse DNS on the announced space resolves under
cgn.sat-co.net. Thecgnlabel is carrier-grade NAT, which is the unmistakable signature of a residential subscriber pool rather than infrastructure or business assignments.
Notable
- The AS announces around 35 IPv4 prefixes, almost all small, plus IPv6. That fragmented shape is typical of a rural ILEC that has accumulated address space in small increments over decades rather than receiving one large allocation.
- The company has also participated in a regional broadband joint venture with a local electric cooperative, a common pattern for extending fibre into sparsely populated areas where neither party could justify the build alone.
Interesting
- The ASN is a genuine 1996 ARIN registration. Small rural telephone companies were among the earliest non-academic organisations to run their own autonomous systems, because being the only carrier in a county leaves no one else to route on your behalf.

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.
