Summary
eStruxture Data Centers
hosting business infrastructure
Five different registrants under one AS, and one of them is a corporate registration number instead of a name.
What it's used for
- A data centre operator. 6,656 addresses across 13 IPv4 prefixes, the IPv6 block
2600:3000:5100::/40, and nine observed BGP neighbours.
Notable
148.66.252.0/22is registered toC06270771, an identifier where a company name belongs.- Other blocks belong to the operator, to a computer technologies firm, to a carrier, and to a research and education network.
- Seven blocks share netname
EDC-83despite sitting in four unrelated parent ranges. - One block is netname
NETEL-ARIN-BLK09, naming a predecessor, a registry and a counter. - Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- A registrant field holding a filing number is the record working as a database key and failing as a document. Whoever reads it has to look the number up in a national companies register before they know who to contact, and abuse handling rarely gets that far.
- A research network's block routed by a commercial data centre is the visible edge of a colocation arrangement: the university network keeps its registration and hands the routing to the building.
- Seven blocks under one netname makes the operator's own records the least specific of the five.

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 1,771 prefixes, as published 2026-10-15. 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.
