Migrating DNS from ISP to in house -

[jonks]

We currently host websites for a number of company's. At present our ISP has our DNS. We want to become our own ISP and host our own DNS servers. How do will migrate over to a new Internet connection and use our own DNS servers and not have any down time beacause of the time needed to propagate our new routes through DNS over the world.

I hope this is understandable , thanks in advance.

well, if u wanna house your own DNS, then am afraid down time is an option you may have to consider..... when u decide to change the authoritative name servers for your domain from Network Solutions, u will have a down time of at least 24 hours, as the new records are propagated over the net.....

one way to avoid downtime would be for u to configure DNS servers at your place with your DNS info, and run them as the primary and secondary for your domain... and then ask your ISP to transfer a copy of the records to their DNS server and play secondary DNS server to your domain.... the Network Solutions database has your ISP as the primary authority for your domain, so to begin the migration, u may ask Network Solutions to setup your secondary DNS server as the secondary authoritative DNS server for the domain, after your ISPs DNS server..... once this has propagated, u should then again ask Network Solutions to setup their database so that your primary DNS server becomes the primary authority for your domain... taking the ISP out of the picture.. but maintaining uptime for your domain, as when the ISP has been dumped, your domain records will be handled and resolved by the secondary DNS server u setup at your place, until the records for your primary DNS server have been propagated, after which your primary should handle all requests.....

remember though, that u will need a public IP address for the primary and secondary DNS servers at your place so that they can be easily reached over the internet to answer queries during the migration...

good luck..

Hey Jonks,

If your websites are just static meaning there are no databases collecting information, the switch is easy to do without downtime. Just setup your websites on your webserver (making sure it is accessible via the outside) and ask your ISP to point all traffic to them. Then configure your dns servers (making sure they are accessible via the outside) to point traffic to the same location and send a change request in to make your dns servers authoritative for your domain.

As long as you have a copy of your website in-house and at your ISP, there will be no downtime as traffic migrates from the isp to your in-house servers.

Good luck,
