AS203008 — Unicast Unicast, Ltd.

AS203008 announces 2 IPv4 prefixes covering 1,024 addresses and 1 IPv6 prefixes.

About this network

The AS handle UNICAST is held by Unicast, Ltd., which operates the Merlin-Telekom brand.

What it's used for

• The address space carries residential and business internet access, evidenced by the netname MERLIN2 and reverse DNS entries such as 128-58-42-31.merlin.ua and 126-247-128-31.merlin.ua.
• The network announces 1024 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 11 observed neighbours; this ratio of modest address space against a moderate number of peers indicates a regional access provider rather than a transit hub.
• Traffic from this AS consists of subscriber eyeballs and local business endpoints served by the Merlin-Telekom brand in Ukraine.

Notable

• The RDAP registrants for both announced IPv4 prefixes list "Merlin-Telekom" LLC, which aligns with the reverse DNS branding despite the AS holder being registered as Unicast, Ltd.
• The address inventory is compact, consisting of two /23 blocks in the 31.0.0.0/8 range and a single /32 IPv6 prefix.
