isp residential russia cable

The AS handle ARTCON-AS is held by Alpha Online Ltd.

What it's used for

  • The address space is registered under the netname RU-ALPHA-20020809 with registrant Alpha Online Ltd, indicating a dedicated corporate estate for the operator.
  • The AS announces 2560 IPv4 addresses across 6 prefixes and maintains 11 observed neighbours, a ratio consistent with a regional access or ISP network rather than a transit provider.

Notable

  • All six announced prefixes share the same netname and registrant, Alpha Online Ltd, confirming a unified ownership structure for the inventory.
  • The address inventory consists of contiguous blocks within the 81.94.32.0/20 range, including a /22 and several /24s, suggesting a consolidated allocation for a single service provider.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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.
