Summary
RETN Limited
transit backbone legacy
RETN-AS is RETN Limited, a large independent international transit carrier operating a backbone across Europe, the CIS, the Caucasus, Central Asia and onward to Asia and North America.
What it's used for
Wholesale IP transit, wavelength and Ethernet services. The role is unmistakable in the routing data: only ~41k addresses of directly announced IPv4 space but ~3,168 observed BGP neighbours, the signature of a carrier whose value is interconnection rather than address holdings. Under the neighbour-count-beats-address-count rule this is a transit backbone, not an eyeball or hosting network.
Notable
The announced prefixes are a scatter of small blocks (many /24s and a few /22–/19s) drawn from ranges RETN carries for customers. Sampled reverse DNS on several of them resolves to rt01.beget.ru-style router names, i.e. downstream customer infrastructure (Beget, a Russian host), riding RETN transit rather than RETN's own eyeball space.
Interesting
RETN is one of the more prominent independent (non-incumbent) carriers bridging Western Europe and the former-Soviet region, widely present at European internet exchanges.
