Using Instant6 Your IPv4 website immediately becomes visible to IPv6
users. No risk, no pain, no disruption, no changes to your content,
service provider or equipment!
There are no restrictions as we only need to receive the domain name.
Since creating the web form we have updated our scripts so that the www will automatically be removed (where appropriate). The web page is reflecting this fact and we just wanted to save the user some typing!
There's nothing stopping you from using any prefix you like whether it be www or not.
the only real restriction is that we cannot support HTTPS (port 443) access - apart from that the facility will simply just work.
Please keep us informed of your experiences we are keen to make it as simple and easy to use as we possibly can.
