Hi, Robert!

After further documenting, it seems that linux can only provide IPv4 interfaces (for more info, see [1], check for SIOCGIFCONF). In order to support IPv6, we need to find a different way to get the addresses. Please open a feature request on our tracker[2], and we will check how to support this.

Hi Robert,

If you use in the listener definition the name of an interface, it should detect IPV6 too. Is this working ?

Thanks for your input. The second scenario doesn't appear to be an issue.

If opensips can detect the IPV4 address on an interface should it be only a
minor enhancement to detect the IPV6 address?

Hi Robert,

I see here two aspects:

1) how to determine the IP at OpenSIPS startup - you need to perform the
IPv6 detection in a pre-start script and feed it to OpenSIPS. That is
the way it should be

2) if the IP changes during runtime, there is nothing you can do rather
then restarting - OpenSIPS cannot change listeners during runtime.

Using 1.10.5
My ISP provides an IPV6 prefix which unfortunately is not static. My
address does not change spontaneously but if the host is down for a
significant time the address will change.

I thought it would be simply solved by specifying a listening interface in
the configuration file. Unfortunately that only picks up the IPV4
address.

I have a DDNS provider and I can specify a domain name in the
configuration but my concern is that the address bound to the domain name may be stale at the moment that opensips comes up. Does opensips verify
an address obtained through DNS?
