AS13092 announces 3 IPv4 prefixes covering 74,752 addresses and 1 IPv6 prefixes.
About this network
A netname ending in BG that means a city, not the country whose code it is.
What it's used for
- Serbia's academic and research network. 74,752 addresses across three IPv4 prefixes, one IPv6 prefix, and five observed BGP neighbours.
Notable
- The largest block is 147.91.0.0/16, netname UNINET-BG.
- The others are RS-RCUB-20061127 and RS-RCUB-20161209.
- The AS handle is UB-AS, a third abbreviation again.
- Nine addresses were sampled and none returned a name.
Interesting
- BG here abbreviates the capital city, but it is also the two-letter country code for a different country entirely. Netnames carry no schema, so a suffix that looks like a country code may be a city, a building, a department or nothing. Anyone parsing these labels automatically will get this wrong, and there is no field that would tell them.
- Four abbreviations for one organisation across the handle, the holder field and two netname generations: the university, the computing centre that ran the network first, and the national academic network that runs it now. The record is a chain of custody nobody ever tidied.
- A /16 alongside a modern IPv6 allocation is the usual academic pattern: early address space granted generously when networks were universities, kept ever since.
