It has been several hours since I renewed my domain registration but DNS queries are still returning the previous IP address for my domain. Here is what I have done to troubleshoot:

1) I can see that the new IP address is 99.93.15.153
2) The previous IP address is 162.216.242.208
3) I have run the dynu IP update script with the following response, showing that the script is working.
Saving to: ‘update?myip=99.93.15.153&username= .....
4) I cleared the DNS cache on my linux host, but I still get the previous IP address returned when I do a nslookup or dig, as follows:

;; ANSWER SECTION:
funkietown.com. 107 IN A 162.216.242.208

;; AUTHORITY SECTION:
funkietown.com. 107 IN NS dns2.anycast.dynu.com.
funkietown.com. 107 IN NS dns1.anycast.dynu.com.

;; ADDITIONAL SECTION:
dns1.anycast.dynu.com. 107 IN A 162.216.242.224
dns2.anycast.dynu.com. 107 IN A 45.79.53.60

5) Note that I did the same on my iMac, which is on the same network, with the same results.

6) Looking at the firewall configuration I can see that the WAN IP is 99.93.15.153

Thanks in advance,
Bill Jones
