I have three domains all pointing to the same machine (a Synology doing virtual hosting). One of them has the current DHCP assigned address, but the two others have a previous DHCP address. The three domains and their current addresses are:

illuminateye.com 50.53.4.122 # correct
braithwaites.net 50.39.124.112 # old address
softwareengineeringllc.com 50.39.124.112 # old address

Is there a way to force a refresh or to guarantee that when my DHCP address changes that all three will pick it up?

Thanks,
