hi I can access my website with this IP 119.234 but whenever it switches to 220.255 i cannot access my website. After that it will takes an hour to get updated to 119.234, only then i can access my site. It has always been from 119.234 to 220.255 and it always takes an hour to update back to 119.234. How do i shorted the update time and how do i not getting that 220.255? Thanks |

Without more information we can't really help you. Are you using the Dynamic DNS service to host a web site? If so where are you performing updates from? |

First thing is to check that you have configured a short TTL for your hostname, e.g. 60 seconds instead of 4 hours. Second thing is to flush your local resolver cache if you can't resolve your hostname to the correct IP address: Further, as you seem to be provided with totally different IP addresses, do you have two ISP's with two different internet connections (dual WAN)? Maybe randomly load-balancing? Cry Havok may be right that your router doesn't update timely enough. Are there any log entries in the router regarding successful or failed DDNS updates, and when these happened? Also, in case you have Dynamic DNS Pro or Custom DNS, you should check your update logs at DynDNS to see if the updates were performed belated. |

I am using the router ddns. I do not have 2 isp in fact both ip came from the same isp. the custom dns ttl is already 20 sec by default. but i still don't quite get it why it takes an hour to update. Thks |

It sounds like it may be a problem with the router not performing the update fast enough. Have you tried using a software client instead? |
