Hi to all!
I'm trying to teach myself to work with IPv6.
On a Stretch client I'd like to have manually set static IPv6 addresses.
But what I get are SLAAC addresses with $prefix + MAC-derived according to the
IEEE-Tutorial EUI-64 .
I can cope with a SLAAC address AND an additional manual static address on the
same interface - no problem - but what is going on here? Why is the manual
address in the file "/etc/network/interfaces" ignored?
What is it that I don't understand?
I don't have such problem with OpenBSD-clients - only with Debian Stretch.
Is it a bug, a misconfiguration or is it me misunderstanding IPv6 address
schemes?
excerpt of my /etc/network/interfaces:
# The primary network interface
auto enp3s0
allow-hotplug enp3s0
iface enp3s0 inet static
address 192.168.12.21
netmask 255.255.255.0
network 192.168.12.0
gateway 192.168.12.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers nnn.nnn.nnn.nnn nnn.nnn.nnn.nnn 2001:470:20::2
74.82.42.42
dns-search MYDOMAIN.co.py
# /48 network obtained from HE which allows subnets
iface enp3s0 inet6 static
address 2001:470:7075:e2::21
netmask 64
gateway 2001:470:7075:e2::
Anyway I get ip addr:
2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP
group default qlen 1000
link/ether 78:24:af:37:6d:60 brd ff:ff:ff:ff:ff:ff
inet 192.168.12.21/24 brd 192.168.12.255 scope global enp3s0
valid_lft forever preferred_lft forever
inet6 2001:470:7075:e2:7a24:afff:fe37:6d60/64 scope global mngtmpaddr \
dynamic
valid_lft 2591999sec preferred_lft 604799sec
inet6 fe80::7a24:afff:fe37:6d60/64 scope link
valid_lft forever preferred_lft forever
Ideally I'd like static private addresses to route through to the IN but
static manual addresses used only in my internal network. But that will be an
exercise for later.
What about "autoconf 0" in /etc/network/interfaces - would that help?
But according to man interfaces that is the default - or isn't it?
Or would
iface enp3s0 inet6 static
address 2001:470:7075:e2::21/64
gateway 2001:470:7075:e2::
be any better?
Thanks for your consideration.
