Residential ARIN Cable/DSL/ISP
Summary
FastNet
isp telecom business
A lettered series of netnames that skips from C to G, and two reverse-naming schemes that disagree about which way an address runs.
What it's used for
- A rural broadband provider. 44,288 addresses across twenty-five IPv4 prefixes, the IPv6 block
2607:8600::/32, and nine observed BGP neighbours.
Notable
- Five blocks are netname
DOUGLAS-FAST-NET-plus a single letter, using A, B, C, G and H. - Two more are
DOUGLASCTYOR-64andDOUGLASCTYOR-199, a county, a state code and the block's first octet, registered to the county itself. 198.237.16.0/20is netnameDOUGLAS-ESD, registered to an education service district.- Two blocks are netname
COGENT-A, registered to a transit provider. - Some addresses answer as
67-219-228-0.mycomspan.com, with hyphens and a third brand. - Others answer as
100.42.171.254.douglasfast.net, with the address in its normal order and dots.
Interesting
- A lettered series missing three letters means those blocks were returned, transferred or never cut. The gap is the only surviving evidence that they existed at all.
- One provider using hyphens in one zone and dots in another gives two hostnames for two addresses on the same network that a parser has to handle differently, which is the practical cost of a rebrand that only half happened.
- A county government, a school service district and a commercial provider sharing one AS is what rural connectivity actually looks like: whoever could get the space pooled it behind one set of upstreams.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
