AS33425 announces 6 IPv4 prefixes covering 95,232 addresses and 1 IPv6 prefixes.

About this network

The AS handle COREWEAVE is operated by CoreWeave, Inc.

What it's used for

• The address space carries cloud infrastructure, evidenced by the reverse DNS record pe-1.ewr1.coreweave.com and netnames such as COREW-1 and UK-COREWEAVE1-20040428.
• The AS announces 95232 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, while maintaining 129 observed neighbours; this ratio of moderate address space against a high number of peering partners indicates a transit-heavy or large-scale hosting role rather than a residential access network.

Notable

• Registrants align with the announcer, listing CoreWeave, Inc for most prefixes and CoreWeave NOC; CoreWeave UK Limited; Abuse-C Role for the UK block.
• The company rebranded from Atlantic Crypto Corporation around 2019 to focus on AI cloud computing.
• The inventory includes a significant UK-based block (83.228.128.0/18) alongside US-based prefixes, reflecting a global infrastructure footprint.
