AS29226 — MASTERTEL-AS Moscow, Russia

AS29226 announces 40 IPv4 prefixes covering 46,848 addresses and 7 IPv6 prefixes.

About this network

MASTERTEL-AS is operated by JSC Mastertel, a regional internet service provider based in Moscow.

What it's used for

• The address space carries residential and business access traffic, evidenced by reverse DNS entries pointing to in-addr.mastertelecom.ru.
• With 46,336 IPv4 addresses announced across 42 prefixes and 330 observed neighbours, the high neighbour count relative to the address inventory suggests a role focused on peering and transit exchange rather than pure internal corporate segmentation.

Notable

• Registrants for all sampled prefixes consistently list "Mastertel Admins" and "JSC Mastertel", confirming alignment between the AS holder and the address space owners.
• The inventory includes a mix of /19, /20, /21, and /22 blocks, with the largest being 83.69.192.0/19, indicating a substantial but fragmented address estate typical of a growing regional ISP.
