Summary

BGC Group

GB · AI-generated

finance business corporate

BGC-INTERNATIONAL is the autonomous system for BGC Group, a global financial services firm.

What it's used for

  • The address space is registered to Cantor Fitzgerald & Co. with the netname CANTORFITZ, indicating the space carries infrastructure for this investment bank.
  • The AS announces 2048 IPv4 addresses across 7 prefixes and maintains only 2 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access network.

Notable

  • The registrant Cantor Fitzgerald & Co. differs from the AS holder BGC Partners, reflecting the corporate history where BGC acquired Cantor Fitzgerald.
  • The inventory consists of seven /24 and /23 blocks within the 148.106.0.0/16 range, all under the CANTORFITZ netname.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
