Hi Tom,

What you have said does not gel with anything I know about the network.
(I am not involved in setting it up, but I am ICANN staff and I know
the network engineers well - who are not Telstra - as we use them every

There is no NAT in the conference network, and no "C" class. The
networks are an IPv4 /20 and an IPv6 /48, and have been configured since
about a week prior to the start of the official conference week. I
just took the liberty of taking a photo in the NOC room of the network


Maybe there are Skype problems, naturally that can happen, but it is
neither due to the conference network being on a NAT or being limited in
address space.

As well as the conference network, there are one of those roaming WiFi
network provider networks barely visible that you have to pay for. Maybe
your complainant is paying to use that rather than using the free and
abundant ICANN conference network.


Quoting Tom Koltai on Friday June 26, 2009:
| Actually Kim, you are absolutely correct.
| Day 1. - Nat Routing - so many complaints about Skype etc not working.
| Day 2. Telstra donates a "C" class on a first come first served basis.
| A whole "C" class for for 1200 plus delegates.
| Smart thinking those Telstra blokes - Anyone that doesn't get an IP
| number upfriont and doesn't wish to queue up for an available 1 in 4
| allocated ip number will give up waiting and use their mobile access
| data plans.
| Is that real enough for you Kim ?
| As far as Paul Twomey is concerned, I apologise to linkers, I should
| have checked pedigrees before shooting off at the mouth.
| Tom
