View Full Version : Seem-less ip change.

Hi, I want to change an IP on a specific hosting account.

But I obviously don't want down time from performing that change.

Is it possible to change the name servers ip's with registrar. Wait till site goes down because of the ip change. Then change the ip's of the cpanel account in WHM to match the new Name server ip change.

Would that work?

Hope that made sense.

Thanks, :)

Why are you changing the name server IPs? Are you not just trying to give one account a dedicated IP address? Post back more clearly exactly what you want to accomplish.

I want to move "example.com" from Ip xxxx To ip yyyy (the site is currently active)

But doing so takes the site off-line for X amount of time. I am trying to reduce/cut out this down time.

Thanks,

Hi,

A few questions.

1) Is the IP address that you wish to assign is of the same server that your site is hosted? if it is, then you don't want to do edit works at the registrar . Just assign the IP address and then just continue.

Hi,
Yeah its on the same server, Thing is I attempted to change the IP and the site went down.

When you change the IP are you able to access it by IP? If yes then that is a DNS propagation issue. Tune your TTL on the DNS server to a really low number, wait the length of the original TTL setting and then change the IP. Remember to change the TTL back to its original setting after some time.

And for absolutely 0 downtime, use iptables to forward the requests to the old ip to the new ip, so people who didn't get the new IP from DNS will still get the site till the dns update propagates out to them.

Hi JCarlin6,

Is your issue resolved? Have you been able to assign new IP address for the domain?
