Summary

Sky Engineering LLC

Russian Federation · AI-generated

isp cable dsl russia

SKY-EN is operated by Sky Engineering LLC.

What it's used for

  • The address space carries residential and business connectivity, evidenced by the netname SkyIng_NAT on the 83.219.234.0/24 prefix and the registrant Sky Engineering LLC for 185.145.124.0/22.
  • The AS announces 1280 IPv4 addresses across 2 prefixes while maintaining 40 observed neighbours, a ratio that indicates a transit or peering-heavy role rather than a large-scale access network.
  • As a Cable/DSL/ISP, the traffic consists of subscriber internet access and data services for end-users in the Russian Federation.

Notable

  • Registrants align with the announcer for the primary block, with Sky Engineering LLC listed for 185.145.124.0/22, while the secondary block 83.219.234.0/24 is registered to OBLCOM NOC.
  • The address inventory is small and fragmented, consisting of two distinct IPv4 prefixes with no IPv6 announcements.

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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
