Summary
Fidium
isp telecom infrastructure
The IPv6 announcement is a textbook binary decomposition, and the reverse names still carry a retired brand.
What it's used for
- A residential and business broadband network. 492,544 addresses across 263 IPv4 prefixes plus 29 IPv6 prefixes, with 51 observed BGP neighbours.
Notable
- The largest blocks are
70.8.0.0/16,163.252.0.0/16,69.53.0.0/17and216.212.0.0/18, all under the netnameCC-4441and registered toFidium. - The IPv6 space is
2604:6e00::/40, announced alongside a descending ladder of its own sub-blocks: two/48s, then/47,/46,/45,/44,/43,/42and/41. - Reverse names take the form
70-8-191-254.mnchnh.fidium.ccidns.net, with a six-character site code ending in a two-letter state abbreviation. - One sampled address answered to
pool-70-105-247-254.port.east.myfairpoint.netinstead. 72.95.96.0/19registers toAmerican Registry for Internet Numbersunder the netnameNET72.
Interesting
- Each of those IPv6 prefixes covers exactly the space the previous ones do not, so together they tile the
/40completely. Announcing a block that way, rather than as one aggregate, means every piece can be steered independently while the whole remains contiguous. - The site codes name three different states in a sample of six, which is what a regional telephone company that grew by acquisition looks like from the reverse DNS alone.
- One address still answers under an older brand's domain. Renaming a company is easy; renaming every address in half a million is a migration that runs for years, and the stragglers are visible to anyone who queries them.
- The block registering to the registry itself, rather than to a customer, means the lookup landed on a parent allocation instead of an assignment.

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: 440 networks and 1,773 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.
