npub1upkp7fd7rc3lrjg23r8gy0wc723vze7mxlx5984ut6zurjzpf5xss4tcwy (npub1upk…tcwy) DNS data is normally updated centrally and copied out to other servers which resolvers query. Sometimes the process of copying changes breaks, so a server that is queried by resolvers is out-of-date. This breakage is what these tools detect.
You cannot simply query all of the IP addresses from a single location to detect the breakage, since many DNS services use anycast, so the same IP address appears in many physical location.
