IPv6 network can be used for connecting to both IPv6 website and IPv4 website.
- What is the difference between IPv4 over IPv6 (DS-Lite) and IPv4 (PPPoE)?
The two connections use different communication facilities for connecting to the internet.
IPv4 over IPv6 (DS-Lite) goes through a facility which is less congested and therefore less likely to cause a slowdown.
- If I apply for IPv4 over IPv6 (DS-Lite), will I not be able to use IPv4 (PPPoE) anymore?
You can continue using IPv4 (PPPoE) as long as the service you are using offers IPv4 (PPPoE) as a standard feature.
