New Report Questions IPv4 Exhaustion

A new study by Zscaler has called into question the previous received wisdom
that IPv4 addresses are running out and forcing the move to IPv6. As reported on
The Register, Zscaler claims that much of the IPv4 space is not utilized to
provide public, internet-facing services or content.


"Mike Geide, senior security researcher for Zscaler, explained: 'Allocated,
public IPv4 space by nature is used to provide internet accessible services and
content. Web, mail, and DNS make up the majority of these Internet services.'

"The firm's findings were drawn from a study of sites visited by Zscaler
customers, which it reckons provides good insight into the portions of the web
that are being leveraged by enterprises.

"'From Zscaler's large and diverse customer base and our billions of web
transactions serviced, we are able to infer that the large amount of 'untouched'
IP space from our customers is a good representation of internet as a whole,'
said Geide. 'In other words, much of the IPv4 space is not utilized to provide
public, internet-facing services or content.'"
