I have re-checked, and the IPv6 address appears to have settled, and that could be true, although I am unable to check at the moment. So far I am not sure about DNS -- Chris Bell Website chrisbell.org.uk -- GLLUG mailing list GLLUG@mailman.lug.org.uk https://mailman.lug.org.uk/mailman/listinfo/gllug
Re: [GLLUG] IPv6 addresses
Hi, I think something associated with the ipv6 disussion and ISPs. Although they might give you ipv6 addresses, their dsl router probably provides no firewalling for it. I added my own firewall for ipv6. Kind regards James -- GLLUG mailing list GLLUG@mailman.lug.org.uk https://mailman.lug.org.uk/mailman/listinfo/gllug

The IPv4 address was expected to be dynamic despite BT claiming to have sufficient IPv4 addresses, while the IPv6 address so far has had a static /48 but dynamic /64. Is there a cost involved in providing a static address, or are UK customers considered to be incapable of safely using a static address? Perhaps it just allows them to charge extra for a "business" broadband. I'm not completely sure how you have static /48 but dynamic /64. Can you not assign yourself a fixed /64 from the /48 if that's what you want? If you're going to be publishing the /64 in DNS somewhere then <48-prefix>:::/64 would probably make sense. If you're not then some random 16 bits might make more sense. Tim. -- GLLUG mailing list GLLUG@mailman.lug.org.uk https://mailman.lug.org.uk/mailman/listinfo/gllug
