Advanced Usage

Daemonize

The most common way to use noipv6 is with a supervisor such as Systemd. But noipv6 can run as a daemon on its own.

# noipv6 will fork into the background, drop privileges and write the new pid to a file.
noipv6 --daemonize --daemon-user nobody --daemon-group nogroup --daemon-pid-file /var/run/noipv6.pid

Perform a single update to a specific IP

source /etc/noipv6.conf && noipv6 --ip-method static:192.168.1.1 --once

Use Custom DNS HTTP Method

noipv6 --ip-method https://myip.dnsomatic.com
noipv6 --ip-method http://ifconfig.me/ip

Use Custom DNS IP Method

noipv6 --ip-method dns:<nameserver>:<port>:<qname>:<record type>
