Public IPv6 addresses are allocated to all users. CGNAT is used for IPv4 , which may affect IPv4 port forwarding.
IPv6 Support
Each Connect Fibre customer is allocated two IPv6 addresses:
- One is used as the address for the Connect Fibre router,
- the second is a /56 prefix that allows the Connect Fibre router to delegate individual prefixes to any connected IPv6 capable address - up to 256
These IPv6 addresses allow supported devices to connect to other IPv6 servers and devices.
IPv4 Support
Due to the worldwide shortage of IPv4 addresses, we use Carrier Grade Nat (CGNAT) which allows for more efficient use of our IPv4 address range.
There are some applications that may be affected by this, including online gaming (e.g. Playstation 5s), VPNs, P2P applications and hosting at home. Port forwarding can help with this.
In order for port forwarding to work, you’ll need a static IPv4 address instead of CGNAT.
Static IPs are available for £5/mth and can be added via the Dashboard.
