No, your problem is in no way similar, because this thread is about domain registration, not about DynDNS hostnames. And ping is not a reliable tool to confirm your IP address as you can see. Instead you use a DNS tool for this. You can also logon to your account to see the currently assigned IP address for your hostname.
Hi TravDog95, I've spun your comment off to a thread on its own so that it can be addressed on topic and not get buried in another that isn't directly related to the issue. Hopefully this will put more eyes on it so more users can assist
