We usually use IPs, although with a local DNS it removes our dependency on external services while retaining the flexibility of hostname. The DNS will automatically update the zone files every night from one of our several DNS servers, to keep the cache fresh. Some checks, though (such as http retrieves) we always do via hostnames as this more closely matches a user experience, and allows us to catch DNS changes that break a web site. A local DNS helps here as it means again no dependency on other servers (if we lose communication with ALL the DNS servers for 4 days (long enough for the zone to expire) then I think someone would have already noticed!)
