[AusNOG] Telstra run out of IPv4 - goes CGNAT

[Jonathan Thorpe]

Hi All,

It’s disappointing that ISPs still show no sign of delivering IPv6 to consumers, even on an opt-in basis despite scrambling to deploy CGN.

One has to wonder if Internode had been bought out before deploying IPv6, if we’d have any consumer ISPs providing IPv6 at all?

Given that CGN requires some re-architecture of the network to work, it would be nice to see as much effort going into deploying dual-stack at the same time.

Aside from increased support from theoretical CPE incompatibilities if its turned on, what are some of the challenges stopping people deploying IPv6 at the same time as doing CGN?

Kind Regards,
Jonathan

Hi all,

I am surprised no one talked about this yesterday

http://www.itnews.com.au/News/401918,telstra-runs-out-of-ipv4-addresses.aspx

This is something I have been saying will happen for a long time now, but forgetting about the Data Retention issue and talking about the CGNAT one, I would be interested to see how many ISPs in Australia are running CGNAT and if they would share their experiences with the rest of us.

Does anyone think this large scale rollout of CGNAT will have a backlash from users? or will no one even notice?

I know of a couple of ISPs running the A10 vThunder CGN boxes, and I am indeed running them on a few ISPs... and for small ISPs they are excellent.  Good price, great performance, easy to manage.  We've also not had a single customer ever complain about things not working.

I'd be interested also to hear of other vendor solutions being deployed out there, how they are working and deal with the common problems, how they scale and most importantly (for me) is the price point and are they appropriate for small (sub 10k) ISPs.
