AS13445 — WEBEX

Network type: hosting

AS13445 announces 45 IPv4 prefixes covering 340,992 addresses and 86 IPv6 prefixes.

About this network

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.
• 62.109.192.0/18 is netname NL-WEBEX-20021101, registered to a B.V. entity of the same brand.
• Announcements are heavily split: 23.89.0.0 alone 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.
