[OpenSIPS-Users] How to ensure current IPV6 listening address

[Robert Dyck]

Thank you for investigating this.

To improve the chance of Opensips getting the current IP address from the FQDN 
I employed the NetworkManager dispatcher to send an immediate update to the 
name server. I am sure that one could parse the output of 
'ip addr" and somehow update opensips.cfg but bash scripts are a mystery to 
me.
