Redirect Subdomain to another ip address or url

I have a tumblr site.We can use our own domain instead tumbr address, redirect our domain to tumblr. Not only a domain,we also can redirect a subdomain to tumblr. It’s easy. Go to our domain control panel. Choose your DNS Zone. We must point the domain’s A-Record to tumblr’s ip address. Add a DNS Record : host A ip_address or for example test.com A 72.32.231.8 (domain) or test.test.com A 72.32.231.8 (subdomain).Don’t use plesk’ or cpanel’s subdomain services to create an A-record, ifwe use this, plesk or cpanel actually create a subdomain with a directory and an ftp for the subdomain. We don’t need this.

Log in to tumblr, open Settings inside Account drop down menu. Choose ‘use a custom domain name’ and type a domain name or a subdomain name. Save our new settings. We may need to wait up to 72 hours or less for the change to take effect.
