networking - How does IPv6 subnetting work and how does it …
网页Using a subnet prefix length other than a /64 will break many features of IPv6, including Neighbor Discovery (ND), Secure Neighbor Discovery (SEND) [RFC3971], privacy extensions [RFC4941], parts of Mobile IPv6 [RFC4866], Protocol Independent Multicast - Sparse Mode (PIM-SM) with Embedded-RP [RFC3956], and Site Multihoming by IPv6 …
subnet - IPv6 subnetting a /64 - what will break, and how to work ...
网页2015年8月18日 · IPv6 is not a fan of smaller subnets, however the only thing that is supposed to break, that I'm aware of, is SLAAC. You'll have problems with bugs and assumptions in some IPv6 stacks, which just blindly assume "/64 == subnet", but that's a bug, not a feature, and you can beat up on the vendor to fix it.
How ISPs will assign IPs /subnets for end users in IPv6
网页I have the impression that even though ISP assigns subnets to end users, the protocols would act different here. In a IPv4 network, an user with a router would turn on DHCP relay in order to other nodes behind this router have IPs assigned. In a IPv6 network, there is no need for DHCP (in most cases) as a node can be autoconfigured using NDP.
How can we receive a global ipv6 subnet? - Server Fault
网页2011年7月22日 · I might be reading too much into your question, but you said you wanted a routed IPv6 subnet. The only way your are going to get a route-able subnet without your ISP being involved is through a broker. Period. If you don't need a routed address you can get a unique-local-address. This is the IPv6 equivalent of the 10.x.x.x address space.
Adding a whole IPv6 /64 block to an network interface on debian
网页22. I tried adding a whole IPv6 (/64) block to an interface using. ip route add local 2001:41d0:2:ad64::/64 dev lo. like described here on my Debian server, but I seem to be missing something.

How to get an IPv6 subnet to use in Docker? - Server Fault
网页2020年5月5日 · 1. How to get an IPv6 subnet to use in Docker? Ask your provider, ISP, or whatever for a delegation of address space. If you only have a /64 you don't have enough. Ideally you should be able to request a /48, though if they are being stingy they might give you something like a /56.

What are use cases for getting an ipv6 /64 subnet per server
网页2021年11月17日 · 1. One of the cases where having /64 IPv6 subnet for single server is important is email sending. Most of the antispam blacklists block on at least /64 subnet level, sometimes (repeating offenders) even on larger subnets. Spamhaus documents this under "IPv6 Blocklist minimum range" here.
