Summary

cdn dns infrastructure

GCORELABSSA-AS-AP is operated by Gcore.

What it's used for

  • The address space carries infrastructure endpoints, evidenced by the netname LU-GCORELABS-ZA on the 78.111.101.0/24 prefix.
  • The AS announces 768 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, self-contained infrastructure footprint rather than a transit or access network.
  • Traffic from this AS consists of web content delivery, DNS resolution, and API endpoints, consistent with Gcore's business as a CDN and DNS provider.

Notable

  • Registrants do not fully align with the announcer; 195.13.54.0/23 is registered to Lir Admin; DomainContext Inc.; Abuse-C Role under netname US-DOMAINCONTEXT-20191101, while 78.111.101.0/24 is registered to ABUSE CONTACT under netname LU-GCORELABS-ZA.
  • G-Core Labs S.A. formally adopted the shorter name Gcore, maintaining its established identity while shortening its trademark.
  • The inventory consists of two distinct IPv4 prefixes in Singapore, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
