we are about o move location and it would be really handy if we could get several servers to have multiple dns records,<br />
current site has totally differnt external ips to new site.<br />
<br />
email, fine i just add mx records with differnt costing.<br />
<br />
but not sure about (A) and www and PTR records<br />
<br />
<br />
site a<br />
web server = 111.111.111.11<br />
ptr = web.mydomain.com &nbsp;111.111.111.11<br />

site b<br />
webserver = 222.222.222.22<br />
ptr = web.mydomain.com &nbsp;222.222.222.22<br />
<br />
<br />
same physical server but need it to work at either site &nbsp;(test on a tuesday) move for real on the friday, as there is a lead time both running with faiilover is preffered.<br />
<br />
isp can only offer round robin on www records, &nbsp;<br />
<br />
yet to have an answer on reverse lookups<br />
<br />
<br />
what other ways could you get round this, surley large farms of web servers have one domain name and multiple IPS?<br />

DNS: can yuou have multiple IPs in use?

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
