Here is a quick trigger to examine the TTL in a DNS response.
Sure, dig or nslookup would be faster. But what if you want to monitor your network for low TTLs in DNS responses? Synthetic checks (i.e., nslookup every 10 seconds) put additional load on your network and DNS infrastructure and they don’t give you an accurate picture of what is actually happening in production.
The solution: a trigger to monitor TTLs as they fly across the wire.
