So, I’m looking to see if there’s a go-to tool for checking DNS propagation times. I need something reliable to make sure everything’s updated across the board. What do you all use when you want to verify DNS changes?
Thanks in advance!
You could use the PerfOps API to build a tool that would:
Enumerate all resolvers by ID (/analytics/dns/resolver)
Collect all the IPs (/analytics/dns/resolver/{resolver_id})
Iterate through them collecting the propagation results (/run/dns-resolve, /run/dns-resolve/{dns_resolve_id}).
Seems relatively inexpensive to mock something up, and then forecast the cost out.
Usually, I utilize WhatsMyDNS.Net
