AS44009 SLEEK-ASN
Hosting RIPE
Summary
Rackspace
hosting cloud business
SLEEK-ASN is held by Rackspace Ltd.
What it's used for
- The space carries Rackspace infrastructure, evidenced by the reverse DNS record
dnscorea.nsmon.ams50.rackspace.netand the netnameAMS50-SEED. - The AS announces 1024 IPv4 addresses and 1 IPv6 prefix with only 1 observed neighbour, indicating a small, self-contained hosting or cloud estate rather than a transit provider.
- Traffic from this AS consists of web/API endpoints and cloud services for Rackspace customers.
Notable
- The RDAP registrant for the announced block is
RXT NLD, which differs from the AS holderRackspace Ltd., suggesting leased address space or historical registry records. - The address inventory consists of a single /22 block, representing a compact and specific allocation.

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.
