QA – I’m having a problem changing DNS on GoDaddy.

I’m moving a client from GoDaddy hosting (GD is still registrar). More than 1hr ago, I changed the DNS to point to the IP at the new host with 1hr TTL. When I check DNS propagation, I see the new IP, but on one online checker, I see 3 IPs–the new one plus 2 owned by GoDaddy that appear nowhere in the DNS. The old website is still appearing although email is working through the new host.

I suspect GD is caching something at thoseĀ 2 IP addresses, but Googling didn’t turn up anything on how to get rid of them or to clear the cache. What’s my best course of action?
