AS6528 SOUTH-TELEP

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. The cgn label 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.
