About this network
An Uzbek internet provider serving residential and business customers.
What it's used for
- Subscriber access. 32,000 addresses across 24 prefixes, four IPv6 announcements, six observed BGP neighbours.
Notable
- The netnames publish the internal address plan. Alongside the dated allocations UZ-SARKOR-20031117, 20060203 and 20141124 sit SARKOR-ROUTERS, SARKOR-SERVERS, SARKOR-STATIC-PPPOE-1, -2, and two blocks named Dynamic-customer-PPPoE-pool-1 and -2 in mixed case.
- The announcements go remarkably small. Below the /18 and the /20 are two /25s, a /26, a /27 and two /28s — sixteen-address blocks announced individually in the global routing table.
- Reverse DNS splits by customer type: general space answers under sk.uz, business space under b2b.sarkor.uz.
- The AS handle names its own upstream, "Sarkor Telecom - Uztelecom, Upstream".
Interesting
- Announcing a /28 is unusual enough that most large networks will not accept it. Filters commonly stop at /24, so those small announcements are visible to direct neighbours and nowhere else — which makes them internal engineering that happens to have leaked into a public dataset.
- Naming a block SARKOR-ROUTERS in the registry tells anyone reading exactly where the network's own infrastructure lives. It is helpful for the operator's peers and equally helpful to anyone else who reads registries for a living.
