Summary

isp eyeball legacy
A Russian regional provider whose reverse DNS is a list of the cities it serves.
What it's used for
- Regional access across several Russian provinces. 68,096 addresses in twenty-seven IPv4 prefixes, two IPv6 blocks, and 65 observed BGP neighbours.
Notable
- The PTR names name the city:
kursk,smolensk,orel,kazan,cherep,ivanovo,ulianovskandmskall appear as labels underptl.ru. - A second family of names under
quantum.ruencodes the netmask instead of the place —bcast224x32,bcast248x8,bcast252x4,subnet0x4. - Twenty-seven prefixes for 68,096 addresses. Blocks like
79.175.0.0/19are announced whole and then again in pieces down to/24.
Interesting
- Those mask names are readable once you see the pattern:
bcast224x32is the broadcast address of a subnet whose mask ends in 224 and which holds 32 addresses, so a/27.248x8is a/29,252x4a/30. Somebody generated a zone file straight from the subnet plan, and the subnetting survives in DNS long after the router configs that produced it. - Two names in the sample lost the dot before the city:
255.15.175.79kazan.ptl.ru. One of them also disagrees with itself, calling79.175.23.254an address in.22.. Generated zones fail quietly, and nothing downstream of a PTR ever checks.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
