AS21738 — ROZINT - Rozint

Network type: residential

AS21738 announces 7 IPv4 prefixes covering 2,816 addresses and 12 IPv6 prefixes.

About this network

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.com and netnames like F4-V4 and NETUTILS.
• 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, and Rozint, 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.
