AS21738 ROZINT
Residential ARIN Cable/DSL/ISP
Summary
Rozint
isp residential business cable
ROZINT is the AS handle for Rozint, a US-based cable and DSL internet service provider.
What it's used for
- The address space carries mixed commercial and residential traffic, evidenced by the reverse DNS record
pl64.plan.successadvisorhub.comand netnames likeF4-V4andNETUTILS. - The AS announces 2048 IPv4 addresses across 4 prefixes and 6 IPv6 prefixes, while maintaining 39 observed neighbours; this ratio of modest address inventory to high peering density indicates a regional access provider rather than a large transit hub.
Notable
- Registrants vary significantly across the announced space, including
F4 Networks,American Registry for Internet Numbers,Internet Utilities NA LLC, andRozint, suggesting a portfolio of acquired or leased address blocks. - The inventory consists of four distinct IPv4 prefixes ranging from a /22 to /24s, alongside a fragmented set of IPv6 /48s and a single /29, reflecting a piecemeal accumulation of resources.

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: 442 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.
