Unclassified RIPE NSP
Summary
Mastertel
isp residential russia regional
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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 432 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.
