Dns updating time

Until the amount of time that is specified by the TTL passes, DNS resolvers will continue to return the old value in response to DNS queries.

If you want to know what the TTL is for a record, perform the following procedure.

When you transferred DNS service to Amazon Route 53, you used the method provided by the registrar for your domain to replace the name servers for the previous DNS service with the four name servers for Route 53.

Domain registrars typically use a TTL (time to live) of 24 to 48 hours for name servers.

/proc/sys/net/ipv4/ip_forward iptables -t nat -A PREROUTING -d [OLD_IP] -p tcp --dport 80 -j DNAT --to-destination [NEW_IP]:80 iptables -t nat -A PREROUTING -d [OLD_IP] -p tcp --dport 443 -j DNAT --to-destination [NEW_IP]:443 iptables -t nat -A POSTROUTING -j MASQUERADE So if the issue is you just created a website and your clients or any given ISP DNS is cached and doesn't show new site yet.

Yes all the other stuff applies ipconfig reset browser etc.

When you transfer DNS service to Amazon Route 53, you need to use the method that is provided by your domain registrar to change the name servers that are associated with your domain.Your best option is to make the transition seamless to the user by using something like mod_proxy with Apache to create a reverse proxy to your new server.That would cause all queries to the old server to still return the proper results and after a few days you would be free to remove the reverse proxy.BUT here's an Idea and something I do from time to time.You can set an alternate network ISP's DNS in the tcpip properties on the NIC properties.
