Summary
Vercara
dns anycast security legacy
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
156.154.0.0/16space 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.
165.156.16.0/21is registered to GE Vernova and its addresses answer understatic.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.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,778 prefixes, as published 2026-10-20. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
