Why IPv6 is not being used more often
Good question and I guess there are many different answers, depending on who you are talking about. In many cases people don’t really analyze the situation or buy in for the belief that there is no need to look at IPv6 for different reasons, such as having enough IPv4 addresses, thinking that IPv6 will not [...]

Can I buy an IPv6 address?
Hi The place to go to for getting IPv6 addresses is your ISP. He will assign a block to you out of his range. For very large global companies in certain cases it is possible to get a block from ARIN directly, but only under certain conditions. Silvia

Can an IPv6 address be spoofed?
Hi Yes. In most cases the same type of attacks can be done in an IPv6 network like in an IPv4 network. Sometimes the tools are a little different. So spoofing can be done with IPv6 and can even be a little more complicated to detect/identify, because an IPv6 interface usually has multiple addresses. Silvia
