What it's used for
- The address space carries residential broadband traffic, evidenced by reverse DNS entries such as
c-74-114-74-0.netflash.netandc-172-86-242-0.netflash.net. - The AS announces 6,912 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining 13 observed neighbours; this ratio of address volume to peering partners indicates an access network rather than a transit provider.
- Traffic from this AS consists of subscriber eyeballs for cable and DSL internet services in North America.

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.
