1. What is IPv6?
The explosive growth in mobile and wireless devices including smartphones, notebook computers, and tablet devices, modems, routers, gaming consoles, has created a need for additional IP addresses. In fact, any equipment that is connected to the Internet must have an IP address to work.
While IPv4 currently supports a maximum of approximately 4.3 billion unique IP addresses, IPv6 solves the shortage by providing 79 billion billion billion times more addresses than IPv4. IPv6 promises improved network performance, security and on-the-go connectivity.

2. What is the main difference between IPv4 and IPv6?
IPv6 is a new IP address scheme that can support many more IP addresses as compared to IPv4. IPv6 promises improved network performance, security and on-the-go connectivity.

3. Will current Internet access be affected?
No, the existing IPv4 services and IPv4 networks will continue to work as per normal for the next 10 years or so.

4. Will the software and hardware that only support IPv4 be affected?
The software and hardware that only support IPv4 will still continue to work with IPv4 addresses as the Internet will still continue to work on IPv4 and co-exist with IPv6 for a long time.

5. Can StarHub’s equipment such as modems, routers and mobile devices still work?
Yes, both IPv4 and IPv6 will co-exist for another 10 years or so. There is no need for you to upgrade your equipment immediately. However, you may wish to consider buying IPv6 ready devices to ensure that they work with an IPv6 service or network.

6. Are there any compatibility issue with existing StarHub issued equipment and 3rd party routers?
There should not be any compatibility issue as both IPv4 and IPv6 will co-exist at the same time for another 10 years or so. StarHub will continue to work towards providing IPv6 ready devices to support this transition.

7. If I configure my own router for IPv6, will I be affected?
If you configure your own IPv6 via public tunnelling, you may possibly experience inefficient IPv6 routes as traffic may not be transmitted through the shortest route path of StarHub Internet network and StarHub’s upstream providers’ networks. If you encounter this issue, please turn off the IPv6 tunnelling service.
