[Serusers]Problem on ipv6

[Ren-Huang Liou]

Hi,

I can not enable ipv6 on ser.

I have been set the following configuration on ser.cfg.
listen=2001:238:202:0:230:1bff:feb8:32b9
listen=140.113.131.41

However, I found the following information on /var/log/message:
Mar 9 20:10:09 TIPRA-41 ser: WARNING: fix_socket_list: could not rev.
resolve 2001:238:202:0:230:1BFF:FEB8:32B9
Mar 9 20:10:09 TIPRA-41 ser: WARNING: fix_socket_list: could not rev.
resolve 2001:238:202:0:230:1BFF:FEB8:32B9

I can't receive any 200 OK ,when I had been sent REGISTER using my
UA(ipv6 enabled).

The following is my "ifconfig" information:

TIPRA-41:/home/rhliou # ifconfig
