We are using your service with gnudip client software.

It seams that it is no longer working since september.

The problem is that gnudip.dynu.com resolve as :

[root@sol ~]# host gnudip.dynu.com
gnudip.dynu.com has address 207.38.70.46
gnudip.dynu.com has address 207.38.69.200
gnudip.dynu.com has IPv6 address 2001:470:1f19:4bf::200

And the first addresse is not responding (the 2 others are responding) :

[root@flows ~]# telnet 207.38.70.46 3495
Trying 207.38.70.46...
telnet: connect to address 207.38.70.46: Connection timed out
