But we should not do anything to preclude privacy-enhancing methods being applied at any layer.
Hi, But how does changing the address prefix provide any possible privacy enhancement at all? It's usually L7 that provides/breaks nearly all of that... Nevertheless, for those people being completely lost with how technology works and to assure their warm&fuzzy feeling while dictating how others should build and run their networks - I would agree to add your proposed text below to the document. ;) Cheers and thnx, Jan
I would argue that the BCOP text should say:
a) ISPs are encouraged to support both stable (persistent) and privacy-oriented (non-persistent) prefixes as options for customers;
b) stable/persistent prefixes are recommended as the default, in the absence of legal requirements to the contrary in any specific country.
I’d also note that the biggest UK IPv6 deployment is a “sticky” /56 to residences; it’s hard for an ISP to guarantee a lifetime stable prefix, but they can take steps to minimise the likelihood of a change being needed.
