From memory if you have a good enough reason, majority of ISP's will

Different ISPs appear to have wildly varying policies, and I have been caught out with this before. A certain ISP does fixed IPs on their cable and business lines, but not home ADSL. They blame another certain ISP for not being able to do this. ;) My current ISP doesn't promise a fixed IP (they say it might change), but I got the same IP address that I had under my account (which I cancelled when I moved from Nelson) when I re-signed up to 2 years later! Best thing to do is just ask, and make it clear that it hugely influences your choice of provider.

For instance, I require a static IP to establish a VPN circuit to the company I work for, thus I had a good enough reason to obtain a static. Incase you're wondering, I use XNET for DSL at home, they may have changed their policies since or maybe I just spoke to the right person, however I don't see why they wont provide you a static unless it was for the purose of reverse DNS for a IRC chat host or something.

G'day,

I'm about to switch ADSL providers, and that caused me to stop and think about dynamic/static IP addresses and ADSL. Mainly because I'll have an always on connection[0], yet I'll still have a dynamic address, or I need to pay $10/month for a static IPv4.

It has been suggested to me that one of the reasons that DSL connections in NZ tend to have dynamic addresses is due to an APNIC policy. Can anyone here point me towards it?

The best I've found is a slide deck from their Internet Resource Management course[1] which says that dynamic addressing is encouraged, but I haven't found any policy documents to back that up.

It fact it seems that APNIC policy is opposite to that. The assumption in the APNIC IPv4 Guidelines[2] is that DSL connections are permanent 'net connections and therefore are normally assigned static IPs.

And yes, I am using dynamic DNS at the moment. It looks like I will continue to do so, but it'd be nicer to have a static IPv4 address. It seems crazy to have to pay for the benefit of an allocated IPv4 address when I'll always be using one anyhow.

Cheers!

I'm not aware of any policy (we do both Dynamic and Static allocations for DSL depending on the account type. Our preference is dynamic as it makes load balancing between POPs easier). It sounds like someone's confused some wording somewhere in 6.2 of IPv4 allocation and assignment guidelines (http://www.apnic.net/policy/ipv4-guidelines.html ) "For services that are intended to connect the Internet on a permanent basis (for example cable, leased line, or DSL services), organisations may make static assignments without the need to provide additional technical justification. Many networks will use dynamic addressing even for permanent connections. This may also be done without the need to provide additional technical justification."

G'day,

Thank you to the people letting us (and me via private email) know who does and doesn't provide static IPs, but can anyone point me towards this mystical APNIC policy?

Or we safely assume that there is no such policy?

Cheers!

Nathan, Section 6.2 explains it for DSL.

Considering further down in the policy, it indicates more information on cable/DSL in section 10, which in my mind anyway clarifies the whole dynamic/static thing. (apnic obviously intend the ranges to be used dynamically, as language in the section indicates that they are interested in "peak usage" etc). Matthew Moyle-Croft wrote:

I think Nathan has kindly demonstrated the confusion from where this meme about APNICs addressing policy may have originated.

Thanks for helping :-)
