In the same way that the Wayback Machine has vast amounts of data of what websites used to look like at arbitrary timepoints, is there any analogous service that keeps track of zonefile changes?
Thankfully, I'm not asking because I've screwed up a client's zone file (which was all my friends' first question :o) but because a site we used to run for a client has been migrated away from us and I was just curious to know when the zone file was updated to point to the new hosting provider.
Is there any way I can look at when the A
and CNAME
records will have changed?
