Summary

GlobalSign

United Kingdom · AI-generated

business infrastructure certificate anycast

The AS handle GLOBALSIGN is held by GMO GlobalSign Ltd.

What it's used for

  • The address space carries infrastructure endpoints, with netnames GLOBALSIGN and GLOBALSIGN-ANYCAST registered to GlobalSign NOC.
  • The AS announces 768 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, peering with 7 neighbours, indicating a focused infrastructure footprint rather than a large access network.
  • Traffic from this AS consists of web and API endpoints for GlobalSign's digital certificate and trust services, including anycast infrastructure for certificate validation and issuance.

Notable

  • Registrants align with the announcer, with both prefixes registered to GlobalSign NOC under netnames GLOBALSIGN and GLOBALSIGN-ANYCAST.
  • The address inventory is compact and finely subdivided, consistent with an internal corporate estate for a global certificate authority.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
