Summary
Cisco Webex
enterprise hosting infrastructure
One netname on almost everything, and a foreign block whose netname carries the date it was created.
What it's used for
- A video conferencing service's network. 342,016 addresses across eighty-seven IPv4 prefixes, one hundred and forty-six IPv6 prefixes, and one hundred and twenty-seven observed BGP neighbours.
Notable
- Nearly every block is netname
WEX, registered to the conferencing subsidiary. 62.109.192.0/18is netnameNL-WEBEX-20021101, registered to aB.V.entity of the same brand.- Announcements are heavily split:
23.89.0.0alone appears as a /18, three /19s and two /20s. - Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- A netname ending in eight digits is a creation date written into the identifier, a convention from a registry era when the name had to encode when the record was made. It fixes this block to the early 2000s, long before the brand became part of its current parent.
- Splitting a /18 into the /19s and /20s inside it, then announcing all of them, is how a service steers traffic. Each fragment can be sent to a different region, and the covering block catches whatever is left.
- One hundred and twenty-seven neighbours for a company that sells meetings is the shape of a service that has to be close to everyone. The peering is the product: latency, not capacity, is what customers notice.

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 1,775 prefixes, as published 2026-10-11. 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.
