Are there any true dynamic DSL providers?

Hi, I was wondering if there any ISP's where IP changes each time you connect. It seems mosts so-called dynamic IP services are actually 'sticky', ie they may not change at all.

BT - I cannot remember ever having the same IP after a reconnection and even after a manual resync it would change.

I believe Plusnet may do on the Value service which does not have a static IP.

When I worked there, many years ago, dynamic IPs were really dynamic and changed each connection.

Still the same, every disconnection on Plusnet Value results in a new IP.

My IP changes (within a range) every day when I switch my router on. ISP is Eclipse.

Orange IPs are not sticky. Probably follows from being BT WBC.

I've often wondered why ISPs bother with dynamic IP addresses these days. I'm assume that back in the mists of time there were enough people with USB modems to provide a churn and allow ISPs to have contended addresses thereby saving money. But today I'd have thought most people remain connected all the time or at least all the time during peak hours. So what's in it for the ISP? I wouldn't have thought enough people wanted a static IP address to make it a significant added value whilst at the same time most people have no need to change their IP address all the time.

My IP on BT changed every time I restarted the router

Dynamic addressing will disappear, I would imagine, with IPv6, and a good thing too. It's difficult to think of valid reasons for dynamic addressing.

In reply to a post by AEP:

Money-saving by the ISP I imagine - fewer need to be allocated to them, and I assume they are not free.

I don't see why that should change with IPv6. Maybe it will. Or at least the price (to the ISP) be lower.
