- Plesk for Linux
On a Plesk for Linux server, a link-local IPv6 address is configured on a network interface:
# ip -6 addr show
inet6 2001:db8:f61:a1ff:0:0:0:80/64 scope link
This IPv6 address is not shown in Tools & Settings > IP Addresses and is still not shown after clicking Reread IP in that menu.
Link-local IPv6 addresses are filtered out by the internal network backend in Plesk for Linux.
Contact the service provider or network administrator to configure the static global IPv6 address on the server.
