About this network

The registrant field has two stray letters, a hyphen and a space in front of the company name.

What it's used for

• A financial services company's network. One IPv4 prefix announced from the United States, no IPv6, two hundred and fifty-six addresses, through two observed BGP neighbours.

Notable

• The registrant is the company name in capitals with two letters and a hyphen prepended, then a space before the name begins. A filing marker never meant to be read as part of the owner is now part of it.
• The netname is the word for a network, then the address written out in four hyphenated parts, then a trailing numeral. It describes position and says nothing about who holds the block.
• All three queried addresses answered, each with three letters, then its own address in four parts with every part padded to three digits by leading zeroes. Those names sit on a carrier's business domain, not the company's.
• The company's name is spelled out in exactly one field. The AS handle reduces it to three initials, two letters for an autonomous system, and a numeral one.

Interesting

• A netname built from the address is what a carrier writes when it hands a customer a block out of its own space. The registry ends up sorted by number rather than by tenant, which suits the carrier and helps nobody trying to identify the network.
• Zero padding exists so hostnames sort in the same order as addresses: a courtesy to text tools that lengthens every name.
