About this network

ORIONTELEKOM-AS is Orion Telekom d.o.o., a Serbian fixed-line ISP based in Belgrade (Zemun).

What it's used for

An access/eyeball network. The AS announces ~301 IPv4 prefixes (~106k addresses) with ~140 observed BGP neighbours. Sampled reverse DNS lands on subscriber and access naming: ip-109-121-55-1.oriontelekom.rs and ADSL pools under adsl-3.sezampro.rs (Sezam Pro, an ISP Orion absorbed), plus mediaworksit.net "free-" pools. This is retail broadband address space, not backbone or hosting infrastructure.

Notable

• One of Serbia's larger alternative fixed operators, offering broadband, TV and business connectivity.
• The sezampro.rs reverse DNS is a fossil of Sezam Pro, an early Serbian ISP whose network Orion took over. The prefix has been announced since 2000.
