Summary

TransTeleCom (TTK)

Russia · AI-generated

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-ASN1 are 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.
