AS16491 announces 16 IPv4 prefixes covering 10,496 addresses and 0 IPv6 prefixes.

About this network

Seventeen prefixes, six naming schemes, three carriers' brands, and one netname that is just an address.

What it's used for

• A satellite provider's network. Seventeen IPv4 prefixes announced from the United States, no IPv6, ten thousand four hundred and ninety-six addresses, through eleven observed BGP neighbours.

Notable

• Three blocks are named by a backbone carrier: its initials, the company's brand cut to five letters, a number, and the address. Two of the three share one netname despite being different blocks.
• Five carry two letters, three for a city, and a digit. Two digits appear, so the scheme distinguishes sites rather than blocks.
• One block is registered to a second company under a netname that includes a year and the words for a primary block. Another is registered to a third carrier and names a brand that carrier absorbed, with the word for legacy in the middle.
• One netname is nothing but the address and its prefix length, hyphenated. It says only where the block is.
• The last block adds a country abbreviation and lists three contacts: an incident response team, the company, and a job description.
• The company's own name is written two ways across the registrant fields, one of them missing the space after the comma.

Interesting

• Two of eighteen queried addresses answered, both naming subscriber connections under a product brand's domain. The service has a name customers know, and it is not the one on the registry record.
• Address space gathered from three carriers is what a provider does when its own allocations run out.
