Thanks everyone for the suggestions. There seems to be many different solutions (as usual).
I have opted for the simple solution of changing my original settings in /etc/modprobe.d/blacklist.conf to:

blacklist ipv6
options ipv6 disable=1

and that works for me. When I am ready for ipv6 I will simply delete these two parameters.

Cheers
