Two IPs for one nameserver?

Posted by radhika, 08-01-2013, 01:05 AM
While I am transfering my sites to new host, I can assign IPs from new host to current nameserver (which already have IPs assigned from my current host)? Thnx .

Before you transfer your site, update your DNS time-to-live values to something low like 300 seconds or even 60 seconds if you have relatively light traffic. This way when it comes time to make the switch to the new host, your changes will propagate through DNS much faster. If you are using a webservice, you can also do a 301 redirect. What I do is create a new temporary domain on the new host and put in a 301 redirect on the original host using .htaccess redirect That way if anyone has a DNS server that has a cached IP for your hostname, they will get redirected until the cache expires and you can turn off the original host altogether.

What I would suggest is below: 1. Transfer all your website data to new hosting provider server and then edit DNS zone records in old hosting control panel and point them to new server IP address. Please make sure that you test website functionality on new server using temporary URL before you make a switch. 2. By this way, your website traffic will start pointing to new server. Once you transfer all the websites to new server just go ahead and change the main IP address of your child nameserver to new server IP address. It will minimize the DNS propagation time.

I am seeing some A entry, mx record etc. There I need to change current host ip address from new host one? (These new ip is from new hosts. right?) One web site has dedicated ip. Which IP i need to point to? You mean like this? http://ip.num.b.er/~username thnx. .

If you're using cPanel, setup DNS clustering, from old to new. Make sure the two actually talk to each other, synchronize ALL records (even ones that don't belong to the server) When all that's done, make sure you synchronize your old backups to the new server, just as an 'in case' measure. CP usually doesn't screw up, but it can. Once you do the first step, I'd suggest changing the nameserver IP's. At that point, it won't matter, they're going to be talking to each other, and it'll be all good
