AS16550 — GOOGLE-PRIVATE-CLOUD

AS16550 announces 5 IPv4 prefixes covering 1,280 addresses and 0 IPv6 prefixes.

About this network

The handle names a private cloud product, and every block belongs to somebody else.

What it's used for

• A cloud provider's network. Four IPv4 prefixes announced from the United States, no IPv6, one thousand and twenty-four addresses, through four observed BGP neighbours.

Notable

• The AS handle joins the holder's name to the words private and cloud, and the name appears on none of the four blocks.
• One block is registered to a national ocean and atmosphere agency, under a netname joining its initials to the name of its own wide-area network.
• Two more belong to a national patent and trademark office and share a single netname: the office's initials and the word for a network.
• The fourth netname is not a name. It is the first and last address of the range with spaces around a hyphen, and its registrant is a carrier's pool of customer addresses.
• Three of twelve queried addresses answered. Each writes the address backwards, then a word meaning fixed, then a word meaning one address answered from many places, then that carrier's domain under a two-letter country suffix.

Interesting

• A cloud provider's AS number carrying government blocks is what a direct interconnect looks like from the routing table. The addresses stay the agency's; the announcement is the provider's.
• The backwards address is the raw form of a reverse-DNS query leaking into the answer: whoever generated the zone used the lookup name and never turned it back round.
• Four blocks, three registrants, none of them the holder. The handle is the only field that agrees.
