About this network

UNICOM-B-AS — the Bulgarian Research and Education Network Association (BREN), Bulgaria's national research and education network (NREN). The RIPE object describes it simply as "NREN - Bulgaria".

What it's used for

• National backbone connectivity for Bulgarian universities, research institutes and academic institutions, and their onward connection to the pan-European research network.
• It announces around 57 IPv4 prefixes, overwhelmingly drawn from the legacy 194.141.0.0/16 Bulgarian academic block, plus IPv6.

Notable

• Institutional, not commercial: the prefixes are member institutions' campuses. BREN provides transit to its members but is not a general ISP.
• The UNICOM-B handle is the network's original name from the early Bulgarian academic networking era and has never been changed.

Interesting

• BREN also supports BGP communities for its transit customers, which is a hint that Bulgarian academic institutions multihome through it much as commercial customers would through a carrier.
