Hosting ARIN
Summary
Lambda
hosting enterprise legacy
LAMBDA-BB is held by Lambda, the San Jose GPU-cloud company (2510 Zanker Rd) that sells deep-learning compute — cloud GPU instances, clusters, servers and workstations. This is a recently reissued AS number, not an old network.
What it's used for
ARIN's registry is explicit: the autnum was registered on 2025-08-27, last changed the same day, under org handle LL-874. Older inventories still label AS11588 with a StackPath handle; that record is stale. Anything you read about this AS's history belongs to a previous holder, and the low AS number says nothing about the age of the network now using it.
The current footprint is small and young-looking: RIS sees 1 IPv4 prefix, 198.145.39.0/24 (256 addresses), 1 IPv6 prefix, 2607:bb40::/32, and 9 observed neighbours. The /24 registers to Lambda itself (LL-4-1). Nine neighbours against a single /24 is not a transit role — it is a well-connected edge, an operator peering at exchanges while carrying very little address space through this particular AS.
That combination reads as early build-out. A /32 of IPv6 is a full provider-sized allocation; a single /24 of IPv4 is a starter block. Lambda's production GPU capacity is not primarily numbered here.
Notable
The classification is hosting because that is the business — rented compute — but note the caveat: this AS carries a fraction of it. Treat AS11588 as Lambda's newly numbered network, and do not attribute its predecessor's routing or reputation to it.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
