Summary
BLC Telecom Oy
residential business telecom finland
SPY-AS is operated by BLC Telecom Oy.
What it's used for
- The address space carries subscriber and business connectivity, evidenced by reverse DNS records pointing to
blcnet.fi(e.g.,46-163-223-255.blcnet.fi,83-146-168-0.blcnet.fi). - The network announces 28,672 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, with only 2 observed routing neighbours, indicating a local access network rather than a transit provider.
- Traffic consists of private and business telecommunications services provided in the Eastern Finland region, including key management and connectivity solutions for residents and companies.
Notable
- All registrants for the announced prefixes are listed as BLC Telecom Oy, consistent with the AS holder.
- The address inventory is composed of five distinct IPv4 blocks, including a /18, a /19, a /21, and two /22s, alongside a single /32 IPv6 prefix.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
