AS16552 — DIGICERT

Network type: hosting

AS16552 announces 35 IPv4 prefixes covering 20,992 addresses and 42 IPv6 prefixes.

About this network

Five brands share one network: the handle, the holder, two reverse-DNS domains, and a fifth on three blocks.

What it's used for

• An anycast DNS network. Thirty-three IPv4 prefixes and two hundred and three IPv6 prefixes announced from the United States, twenty-one thousand two hundred and forty-eight addresses, through two hundred and forty-one observed BGP neighbours.

Notable

• The AS handle is a certificate authority's brand. The holder is a differently named company, and the two share no other field.
• Most netnames are the holder's brand, sometimes with a country code, a city code and a numeral one, sometimes with a two-letter region marking which registry issued the block.
• One puts the country first, runs the company name and a numeral together, and stamps the issue date on the end.
• Three blocks belong to a fifth company entirely, all under one netname of three letters and a four-digit number.
• Two list an incident response team as a registrant object, beside the company written twice in different capitalisation.
• Seventeen of eighteen queried addresses answered across four domains: two consumer DNS brands, the holder's systems domain, and one name-server name.

Interesting

• Two hundred and forty-one neighbours on twenty-one thousand addresses is the signature of anycast: the same addresses announced from many places at once, so the count stays small.
• Two redirection domains under different brands in one record is acquisition residue. Each brand kept its zone; the addresses were pooled underneath.
• A date in a netname records when the block was issued: the one fact here nobody can revise.
