About this network

The netname is not a name at all: it is the address range, written out with spaces.

What it's used for

• A national tax authority's network. Two IPv4 prefixes announced from Chile, no IPv6, and five observed BGP neighbours.

Notable

• Both netnames are the first and last address of the block, separated by a hyphen with a space on each side, so the field holds a range rather than an identifier.
• Spaces inside a netname break the assumption most tooling makes, that the value is a single token.
• The registrant is the agency itself on both blocks, spelled identically.
• The two prefixes are adjacent, a /24 sitting immediately below a /23.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• A registry that puts the range in the name field has decided the name adds nothing, and it is hard to argue. The range is already known from the block, so the label is guaranteed accurate and guaranteed useless, which is the opposite failure to the netnames elsewhere in this range that encode a different address entirely.
• Seven hundred addresses for a country's tax administration is a small public footprint, which fits an agency whose systems face citizens through a handful of services and keep everything else internal.
• Five upstreams for two blocks is a lot of redundancy, and for a tax authority with filing deadlines that is the point.
