Namaste misc, In IPv6, what address prefix/range is recommended for use when assigning multiple addresses to the loopback interface?
The use case is running multiple servers (nsd and unbound) on the same port but different loopback addresses. It is similar to what popped up on the other thread about dig. If I am not wrong, 127.0.0.1/8 is the loopback range in IPv4. On the other hand, in IPv6, there is only one loopback address - ::1/128 [1]. And because there is only one loopback address, I do not know whether: 1) ::2/128, ::3/128 et al are RFC compliant IPv6 loopback addresses. 2) the very idea of running multiple servers on the same port but different loopback addresses is redundant in IPv6. Searching the internet throws up different mechanisms, but no definitive solution. In fact, someone went throught the entire trouble of writing up a draft RFC [3] to assign an address range. But for reasons that I do not know, the draft was allowed to expire.
