+synopsis:
+ Confirm delegation of NS and MX records
+description:
+ Haeredes is primarily useful for ISP network administrators.
+ Customers will occasionally decide to switch hosts without alerting
+ the current host; this can cause two problems:
+
+ * With NS records, the previous host (at the very least) keeps
+ hosting a DNS zone that does nothing. If that host uses their
+ authoritative nameserver as a caching lookup server as well, it
+ may return incorrect results to queries about the domain in
+ question.
+
+ * For MX records, the situation is slightly worse. Most mail servers
+ will immediately accept mail for which the server thinks it is the
+ ultimate destination. If a mail server is configured as the
+ destination for a domain, but it is not the MX for that domain,
+ then mail submitted to that server may possibly be lost. It is
+ therefore important to remove domains from the old mail host as
+ soon as the MX record is changed.
+
+ Haeredes can alert administrators when NS/MX records are changed. More
+ detail and usage examples can be found in the man page.
