anti-ddos isp business security

ANTI-DDOS is the AS handle for NetLab Global, a US-based provider specializing in anti-DDoS protection and internet services.

What it's used for

  • The address space carries infrastructure for DDoS mitigation and general internet services, evidenced by netnames such as NETLAB-CGNT-NET-1 and NETLAB-CGNT-NET-2 registered to NetLab Global.
  • With 6144 IPv4 addresses announced across 11 prefixes and only 2 observed neighbours, the ratio suggests a focused service provider or internal corporate estate rather than a large-scale transit or residential access network.

Notable

  • Registrants are mixed: most prefixes are registered to NetLab Global with netnames like NETLAB-CGNT-NET-1, while two /22 blocks (45.138.68.0/22 and 45.158.20.0/22) are registered to XNNET LIMITED with netnames HK-XNNET-20190807 and HK-XNNET-20190927.
  • The address inventory is finely subdivided into multiple /23 and /24 blocks under the NetLab Global registrant, indicating site-by-site or service-specific segmentation within the corporate estate.

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 1,781 prefixes, as published 2026-10-16. 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.
