AWS Impact Assessment

You’re in the process of decomissioning one of your servers. Before you do that, however, you want to quickly find out what DNS entries will need to be updated in AWS Route 53. Our ‘impact’ tool allows you to check what zones will impacted when changing or removing server ip addresses, neat!

dns-tools impact --cloud aws --oldip <address range>

Example impact report

Surprise, surprise! We have two zones that point to our server not just one like we expected.

As much as people claim “there’s only one record pointing to that IP” we have seen time and again that these claims are false: You need to check the data before you migrate or decomission a workload, if you want to sleep well that night anyway!
