AS6823 TR-3C1B-TELEKOM

TR-3C1B-TELEKOM is 3C1B Telekomünikasyon, a licensed Turkish operator headquartered in Ankara. It sells corporate internet, Metro Ethernet, leased lines, colocation and DDoS protection, plus wholesale interconnect and voice services to other carriers.

What it's used for

• Business connectivity and data-centre services rather than consumer broadband. Reverse DNS on the announced space sorts itself into named pools — metro-pool and metro_customer for Metro Ethernet circuits, statik_pool for static assignments, voip-pool for voice, co-location-pool for hosted kit, and backbone-ip for the network's own routers — all under 3c1b.net.
• The RIPE allocation is described bluntly as "3c1b Customer Networks".

Notable

• The IPv4 footprint is modest (a few thousand addresses) but the AS announces a large amount of IPv6 and peers heavily, including at AMS-IX, DE-CIX and Turk-IX. That combination — small address inventory, wide peering — is the profile of a transit and interconnect business, not of an address-hungry eyeball provider.
• Its wholesale side includes interconnect and regulatory services sold to other Turkish operators, which is why its peer count is out of proportion to its size.

Interesting

• The self-documenting reverse DNS is unusually helpful. Most operators publish opaque templated names; 3C1B labels each pool with the product it belongs to, so the shape of the business is legible from a handful of PTR lookups.
