Summary
NuCDN
cdn hosting business
The AS handle NUCDN is held by NuCDN LLC.
What it's used for
- The address space carries content delivery and web acceleration services, evidenced by netnames like
NUCDN-ARIN-1andNUCDN-ARIN-2, and reverse DNS entries such aslo0-0.bfr1.lhr1.as23393.netandmx2.anti-error.com. - With 13312 IPv4 addresses announced across 13 prefixes and 15 IPv6 prefixes, the network maintains a moderate footprint. The presence of 13 observed neighbours suggests a role focused on content delivery and peering rather than pure transit or residential access.
Notable
- Registrants include NuCDN LLC, ISPrime LLC, Comodo Group Inc., and DNS.com, LLC, indicating a mix of owned infrastructure and leased or acquired address space.
- The address inventory is subdivided into multiple /22 and /23 blocks, reflecting a segmented corporate estate typical of CDN providers managing distinct service tiers or geographic regions.

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 1,784 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.
