The haeredes package

[Tags:agpl, program]

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:

Haeredes can alert administrators when NS/MX records are changed. More detail can be found in the man page.

Examples:

Make sure example.com has the expected name servers, [ab].iana-servers.net:

$ haeredes a.iana-servers.net b.iana-servers.net <<< "example.com"

If you use --no-append-root and your nameservers are rooted, you must remember to supply the trailing dot yourself. Otherwise, you'll get false positives.

$ haeredes --no-append-root \
           a.iana-servers.net b.iana-servers.net \
           <<< "example.com"
Domain "example.com" delegates somewhere else: "b.iana-servers.net." "a.iana-servers.net."

Check orlitzky.com against the expected name servers, using d.gtld-servers.net:

$ haeredes --server 199.7.91.13 dns1.viabit.com dns2.viabit.com \
           <<< "orlitzky.com"

Check orlitzky.com against only one of the expected two nameservers:

$ haeredes dns1.viabit.com <<< "orlitzky.com"
Domain "orlitzky.com." delegates somewhere else: "dns2.viabit.com."

Check a nonexistent domain (we provide no delegates, since we know .bar will not be delegated):

$ haeredes <<< "foo.bar"
Domain "foo.bar." not delegated.
