No. It's about as far into the realms of incorrect that you can go ;)

If you already have a static IPv4 address there is no suggestion that it
will be taken from you.

When you get an IPv6 address it will not be based upon your IPv4 address
unless you specifically use a tunnelling service that does that which
isn't really optimal so it's unlikely. The tunnelling services I've
tried out all allocate normal IPv6 - either as a /128 single IP or a /64
network allocation.

Those with a UKFSN broadband connection (except for C&W LLU based ones)
can get a native IPv6 network allocation already. This runs dual stack
so you have both IPv4 and IPv6.
