Understanding the Domain Name System

Option 1: DNSMadeEasy.com - has an excellent DNS FailOver feature - to ensure 100% uptime, in DC or Iowa. This allows the entry of multiple IPs for the same domain. DNSME pings the site every few minutes. If it is down, then it automatically switches the domain to the backup IP. For example CICorp.com is usually pointing to 67.55.221.10 (Natel in Iowa). If it is down, then CICorp.com points to 67.102.243.10 (Covad in DC).

Question: How to implement Reverse DNS?

Option 2: CIReg DNS Manager - ok, well backed up, and integrated with domain list, but still tedious

Option 3: There must be some way to do it ourselves, in house
