Autonomous system
AS5543 TEST-ASN1
Unclassified RIPE
Summary
TransTeleCom (TTK)
transit legacy
TEST-ASN1 is registered to Joint Stock Company TransTeleCom (TTK), one of Russia's large backbone carriers, built along the national railway network. As the handle suggests, this is an auxiliary or test autonomous system, not TTK's production backbone.
What it's used for
- Very little that is publicly visible. The ASN announces no IPv4 space at all and originates a single IPv6
/48, which is consistent with a lab, test, or special-purpose network rather than a carrier network serving customers.
Notable
- Do not read this ASN as TTK's main network. The parent company is a substantial transit and wholesale carrier, but this AS carries essentially no routed footprint, and its address usage should not be inferred from the parent's business.
- The zero IPv4 count is genuine rather than an artifact: the network's only announcement is IPv6.
Interesting
- Registry handles like
TEST-ASN1are a reminder that not every ASN held by a big carrier is a production network. Some exist for interconnect testing, lab work, or to reserve capability.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, 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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
