When purchasing why ...

[Vector]

is our ip address used? It could easily change. I use a router
and change the base ip address now and again.

Hi,

IP Addresses have to be used because your Internet connection is an IP Address.

However, the IP address is logged at time of purchase, and when revalidating your purchase. This is to help prevent fraud as it is a basic form of identification.

Thanks,

Steve
