Summary
Index Exchange
adtech business global
The AS handle CASALE-MEDIA is operated by Index Exchange Inc., a global digital advertising exchange.
What it's used for
- The address space carries corporate infrastructure for an ad-tech platform, evidenced by netnames such as
CASAL,CASALE-MEDIA, andINDEXEXCHANGEINC-AP. - The AS announces 12,544 IPv4 addresses and 5 IPv6 prefixes across 14 IPv4 blocks, with 10 observed neighbours; this ratio indicates a business network with moderate peering rather than a transit provider.
Notable
- Registrants consistently identify as Index Exchange Inc. across most prefixes, though one /24 (
8.36.162.0/24) is registered to Level 3 Parent, LLC. - The operator was formerly known as Casale Media, a name still reflected in the AS handle and several netnames like
CA-CASALEMEDIA-20041116. - The inventory includes a mix of large blocks (e.g.,
209.204.224.0/20) and smaller /24s, with announced blocks located in Canada.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
