Right, I've had a (brief) look at some of those, and it seems to me that
none offer a better solution than what I've already got.

This thread has now drifted from my asking whether there was any way of
interrogating the hardware to obtain the current IP6 address of host -
apparently not - via an outburst of pedantry, to recommendations on some
off the shelf libraries to update a DNS. I have no problem; I was simply
investigating alternatives to obtaining the current IP6 address, and
thanks to an early reply came up with netifaces, which does a fine job.

As I previously mentioned, I have a well-tried program for keeping my
DNS updated - albeit for IP4 only, and all I want is to extend that for
IP6. Re-inventing the wheel? No, just a natural evolution. I'd be
re-inventing the wheel if I scrapped what I've got, simply to use a
general-purpose library.

If I were starting from scratch, I may well consider a ready-made
client. One drawback that is immediately apparent, and may well be a
misunderstanding on my part, is that any of the clients mentioned
require to be configured with a particular (proprietary) protocol, to
communicate with a (proprietary) dynamic DNS server (DynDNS seems to be
the favourite). Nowhere have I seen NSUpdate mentioned. Maybe there's a
reason for that, but I'm quite happy with NSUpdate.

So, whilst I appreciate all your attempts to help, I think I'll stick
with what I've got.

Thanks all.

Cheers, Tony
