Summary

Ukraine · AI-generated

isp residential ukraine fiber

The AS handle DFC-AS is operated by Digital Optical Communications LTD.

What it's used for

  • The address space carries residential and business traffic, evidenced by reverse DNS entries pointing to xbyte.pro and netnames X-BYTE and DFC-NET.
  • The network announces 1280 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • Registrants for the announced prefixes include Abuse-C Role for the X-BYTE netname and Digital Optical Communications LTD for the DFC-NET netname, aligning with the AS holder.
  • The address inventory consists of two distinct IPv4 blocks: 217.66.96.0/22 and 193.106.211.0/24, with no IPv6 prefixes currently announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
