Keeping this in consideration, how do I upgrade IPv4 to IPv6?
Upgrading to IPv6 with IPv4 configured
- Step 1: Set up the hosts for IPv6. On the hosts on both subnets, do the following:
- Step 2: Set up the router for IPv6.
- Set up IPv6 to be configured on the hosts at boot time.
- Step 4: Set up IPv6 to be configured on the router at boot time.
Subsequently, question is, why are we changing from IPv4 to IPv6? IPv4 has some limitations which are going to present insurmountable problems in the near future. IPv6 will solve those problems by changing the strategy for allocating addresses, making improvements to ease the routing of packets, and making it easier to configure a machine when it first joins the network.
In this manner, how do I get IPv4 instead of IPv6?
You can also change the preferred IP protocol from GUI. To do it, open Control Panel > Network and Internet > Network Connections > Advanced > Advanced Settings. Select your network connection, and set the IPv4 protocol above IPv6 with the green button. You should perform this operation for all available bindings.
Should I use both IPv4 and IPv6?
You should use both IPv4 and IPv6 addresses. Nearly everyone on the Internet currently has an IPv4 address, or is behind a NAT of some kind, and can access IPv4 resources. If you want your site to be reliable for these users, you must serve it via IPv6 (and the ISP must have deployed IPv6).
