Summary
Whiz to Coho, Inc.
isp hosting legacy
COHO-ASN is Whiz to Coho, Inc., an independent internet provider in Hillsboro, Oregon, trading as Coho. It has served the western Portland suburbs — Hillsboro, Beaverton, Forest Grove, North Plains and the surrounding rural west hills — since the mid-1990s, selling fixed-wireless and fibre access alongside hosting and colocation.
What it's used for
Local internet access, with a hosting sideline. RIS observes three IPv4 prefixes — 76.9.240.0/20, 208.67.200.0/21 and 76.9.255.0/24, about 6,144 addresses — plus one IPv6 prefix, 2620:34:e000::/48. Five BGP neighbours is a healthy number of upstreams for a small regional ISP and nowhere near carrier territory.
All three v4 prefixes are registered to the company's own ARIN block (WHIZ-TO-COHO-INC), and the reverse DNS is entirely first-party: host5-76.9.240.whiztocoho.net, host133-76.9.255.whiztocoho.net and 208-67-200-5.coho.net. Self-registered space with self-operated rDNS across the whole announced footprint — a real operator, not a shell fronting leased address space.
Notable
Two brand names, one network: the corporate identity (whiztocoho.net) and the customer-facing one (coho.net) both appear in the rDNS, split cleanly along prefix boundaries.
The PTR names are generic host<n>-<prefix> templates that do not distinguish subscriber lines from hosted servers, so the exact mix of access versus colocation traffic cannot be read out of the routing data alone.
Interesting
The IPv6 allocation is a 2620::/23 block — ARIN direct-assignment space, not a downstream slice from an upstream carrier.

Reputation
Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
