isp residential legacy

BRIGHTOK-AS — BrightNet Oklahoma, the internet arm of the Chickasaw Holding Company (Chickasaw Telephone / CTSI), based in Sulphur, Oklahoma. It sells broadband to homes and businesses across the telephone company's exchanges and, through affiliates, further across the state.

What it's used for

  • Residential broadband — fibre-to-the-home in the newer builds, DSL almost everywhere else, with legacy dial-up still visible in the address space.
  • Business connectivity for customers in the same rural Oklahoma footprint.

Notable

  • Reverse DNS makes the kind unambiguous, and it names three eras of access technology at once: pppoe-216-137-20-9.prkn.ip.ctsiok.net, dsl-66-103-115-30.ip.ctsiok.net, davenport14p44.dial.brightok.net, and static assignments under static.ip.ctsiok.net. Those are subscribers.
  • The inventory is a scatter of ~22 ARIN prefixes (roughly 80k addresses) accumulated over decades — 204.249.192.0/20, 67.206.96.0/19, 69.8.0.0/18, 205.240.128.0/20 and others. Small, contiguous-ish, and all registered to the operator: normal for a rural telco, unlike the scattered multi-RIR /24s that signal address brokering.
  • An IP here is an Oklahoma end user. Do not read it as hosting.

Interesting

  • ctsiok.net and brightok.net are the same operator under two brands: the incumbent telephone company and the broadband name it sells under. The reverse DNS never got unified, which is why both show up in the same AS.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
