Unclassified RIPE
Summary
Vodafone (Cable & Wireless Asia)
enterprise legacy
CWASIA is the former Cable & Wireless Asia-Pacific network, now held by Vodafone Enterprise Equipment Limited following Vodafone's acquisition of Cable & Wireless Worldwide in 2012. The RIPE registration lists a Leeds, UK address and Vodafone's network-control contacts.
What it's used for
- Managed enterprise connectivity — IP-VPN, internet access and managed WAN for multinational corporate customers, with a centre of gravity in Asia.
- Announces a mix of RIPE, APNIC and ARIN blocks, including customer ranges in the Philippines and Europe. Router reverse DNS still resolves under
cwasia.net, with Hong Kong (hkg) among the named sites.
Notable
- This is a corporate/enterprise-services network rather than an eyeball ISP or a hosting platform. Its address space sits at enterprise customer sites and on provider-edge routers.
- The
CWASIAhandle is a fossil: the brand has been gone for over a decade, but the AS number, the handle and thecwasia.netreverse DNS all survive.
Interesting
- Cable & Wireless traces back to the 19th-century submarine telegraph business, and its network assets have been split and resold repeatedly — the Asia arm to Vodafone, the Caribbean/Latin America arm elsewhere. Routing data is often the last place these corporate lineages remain visible.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
