Hallo Michiel,

Well, that is true, yes. But I want my setup to be stable and reliable - and
thus I went this way and won't change it any time soon :)

(DynDNS)
 Mv> For IPv6 it is more difficult than for IPv4.

A little, maybe. At least if you use "standard" DynDNS providers.
Recently, I changed my setup so that I'm my own DynDNS provider for most of
my needs. Thus, "box.imzadi.de" is a CNAME entry for "box.my.imzadi.de", and
the nameserver for the "my.imzadi.de" domain is on my vServer and this gets
the new IP at every change from my home router.

Oh, I don't notice any real slowdown here, it is "fast enough" for my needs :)

Regards,
Anna
