Multiple dns records now supported

We have updated our monitoring software to support multiple ip addresses when checking the dns result returned.

For instance twitter.com has 3 ip addresses for its web server.

twitter.com has address 199.59.148.82
twitter.com has address 199.59.148.82
twitter.com has address 199.59.148.82

So you can now configure the ip address check feature with all three values like so

199.59.148.82,199.59.148.82,199.59.148.82

When the site is checked the ip address returned from the dns lookup will be checked to see it is one in the list.

This will help prevent domain hijacking which happens when a domain registrar is hacked and the ip addresses changed to point to another server.
