Division 4.6.2 Support for IPv6
United Kingdom
It can be assumed that the protocol used on the local networks of the Member States will be TCP/IP. However some sites will be based on version 4 while others will be based on version 6. The network access points must offer the possibility to act as a gateway and must be able to operate independently from the network protocols used in the Central SIS II as well as in the N.SIS II.
