Here is some more information about Vodafone's latest APN list. As most of you will know, APNs can be changed in your device settings/profiles to adjust your connection characteristics. Here is the current APN list:

APN: vodafone 
IP: public
Optmisation: when connection initiated in GPRS coverage
Security: Inbound initiated traffic restricted

APN: direct.vodafone.net.nz
IP: private
Optimisation: Yes, only http traffic
Security: Inbound initiated traffic allowed

APN: opt.vodafone.net.nz
IP: private
Optimisation: Yes
Security: Inbound initiated traffic restricted

MMS settings
Username : 
Password:
WAP Gateway(URL): 172.30.38.3
WAP gateway Port : 8080
MMSC(URL): http://pxt.vodafone.net.nz/pxtsend
MMSC Port: 80

vodafone 
This is the default APN used to access the Internet from the Vodafone network.  It now assigns public IP addresses (previously private NAT addressing).  It will provide users with an optimised experience when the connection is created in GPRS coverage areas. Sessions initiated in 3G / HSDPA coverage will bypass the optimisers.  The security policy used by this APN restricts inbound initiated traffic  – reducing the threat of unsolicited traffic from the internet. 

direct.vodafone.net.nz uses private addresses, as a consequence it uses NAT, so be aware that this will break some applications. It also bypasses the optimisers for all radio access types. 

opt.vodafone.net.nz This APN has been created to provide a fully optimised experience across all network types.  It assigns private NAT’d IP addresses and employs the same security policy as the ‘www’ APN.

You might wonder if you can get a static IP on your mobile connection. The answer is that the public range addresses that Vodafone use are issued by IANA on the basis that they are only to be used for dynamically issued mobile connections. They apparently don't have any available addresses that could be issued staticly, and there would be undesirable complications in doing so anyway. Don't complain too bitterly, it is not that long since all public APNs used private addresses and NAT, which broke more applications.

Cool that'll be useful, perhaps make this as a sticky for the future reference too, instead of being buried as time goes on.

Excellent list - it'll definitely be part of the reference docs for our testing teams.

Thanks for compiling this 8-).

Having had to sort this all out in the past for various M2M projects I have been doing I only wish Vodfone had the sense to publish a straight forward detail such as this on their web site. Also usefull would be the optimum frame/packet characteristics and other various routing behavour of their network. Getting info from them can sometimes be like pulling teeth, and why so hard?, good customer service often is just the simple things.

Cyril, we do have an M2M/Telemetry specialist. If you want any assistance, drop me your details and I will pass them on. This is not the sort of stuff that our standard Customer Service get too many questions about.

Cheers,
tim

Superb! I did have that list "stashed away" but this is much more descriptive!

YES! Sticky this please!

could anyone possibly any light on the  "web.vodafone.net.nz" I have in my list?

The 'web.vodafone.net.nz' APN was initially created to provide a public IP address option.  This was generally used for remote access use as the NAT and private addressing of the 'www.vodafone.net.nz' could not be managed by some VPN solutions.

Since the 'www.vodafone.net.nz' addressing has now been changed to public IP's - the 'web' APN has become redundant.

Users of the 'web' APN will now alias to the 'www' APN.

Fei: ... www.vodafone.net.nz ... The security policy used by this APN restricts inbound initiated traffic ...

Does "restricted" in this context mean inbound initiated is selectively (eg ICMP) blocked by this APN or is all inbound initiated entirely blocked?
Is 121.90....  representative of an address issued by this APN?

Fei: ... Internet ...

Is that just the word "Internet" (no dotted address) on its own? Is the upper-case "I" critical cf lower-case? Is 124.6....  representative of an address  issued by this APN?

That is, is it possible to check whether the intended APN is in use from the ip address issued?
