There is more :-)-O
All teleone name servers allow AXFR (!), so I look at .ZW and find that
they have an interesting concept of glue records:
mahobho.uz.ac.zw. 86400 IN A 22.214.171.124
shrike.uz.ac.zw. 86400 IN A 126.96.36.199
ns1.telone.co.zw. 14400 IN A 188.8.131.52
ns2.telone.co.zw. 14400 IN A 184.108.40.206
mail.healthnet.org.zw. 14400 IN A 220.127.116.11
ns1.zispa.org.zw. 86400 IN A 18.104.22.168
ns.gta.zw. 86400 IN A 22.214.171.124
ns1.mango.zw. 86400 IN A 126.96.36.199
The latter 2 are necessary, the former 6 are not.
Glue records in the parent zone file are often forgotten when changing
their A records in the child zone file and keeping their outdated IP
addresses in the glue (in the parent zone file) can give you very,
very interesting failures.
Putting them into a "grandparent" zone file will make figuring this
out even more difficult...
