About this network

The Bulgarian government's network, with its public wifi and its transit blocks named separately in the registry.

What it's used for

• Connectivity for the Bulgarian government. 8,448 addresses in nine IPv4 prefixes, four observed BGP neighbours, and no IPv6 announced.

Notable

• Four blocks share the netname BG-GOVERNMENT-19990722, which spells its 1999 date in full rather than as 990722.
• A later block is BG-GOVERNMENT-20161212, and one is simply CMBG.
• Three are named for what they carry: BGGOV-WIFI-1-NET, BGGOV-TRANSNET-178 and BGGOV-TRANSNET-179.
• The last two put the third octet of their own address into the name.
• One sampled address answers host254-162.government.bg.

Interesting

• Naming a block WIFI-1 in a public registry is a small act of documentation aimed at whoever comes next. Anyone reading the record learns which addresses belong to the wireless network without asking, which is useful to an administrator and equally useful to anyone else reading.
• The -1 implies a WIFI-2 that either exists elsewhere or was expected to. Sequence numbers in netnames are a plan being written down.
• 19990722 is the second block in this range to spell a 1999 date in full, after AS12536. Together they settle the point that the two-digit and four-digit forms were alternatives available at the same time rather than successive conventions.
