AS12008 — SECURITYSERVICES

Network type: hosting

AS12008 announces 52 IPv4 prefixes covering 26,688 addresses and 36 IPv6 prefixes.

About this network

Vercara runs authoritative and recursive DNS and DDoS protection, the business previously known as Neustar Security Services and before that UltraDNS.

What it's used for

• Anycast DNS and managed DDoS mitigation for enterprise customers. The AS handle is literally SECURITYSERVICES.

Notable

• 52 IPv4 prefixes and 40 IPv6 prefixes for only 27,000 addresses. That ratio is the anycast signature: the same small blocks announced from many locations, so prefix count climbs while address count stays flat. The 156.154.0.0/16 space these come from is the block UltraDNS has used for its resolvers and name servers for decades.
• One announced block is not Vercara's at all. 165.156.16.0/21 is registered to GE Vernova and its addresses answer under static.ge.com. A DDoS mitigation provider announces a customer's prefix in order to pull the traffic through its scrubbing network, which is exactly what this looks like.

Interesting

• The company has been renamed twice without renumbering. The netnames still read SSL-1134, the address block is the original UltraDNS space, and only the corporate registrant has been updated — first to Neustar, then to Vercara after the security division was sold off in 2022.
