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 196.4.80.241 shrike.uz.ac.zw. 86400 IN A 196.4.80.242 ns1.telone.co.zw. 14400 IN A 194.133.122.47 ns2.telone.co.zw. 14400 IN A 194.133.122.42 mail.healthnet.org.zw. 14400 IN A 196.44.176.80 ns1.zispa.org.zw. 86400 IN A 196.2.64.16 ns.gta.zw. 86400 IN A 209.88.90.3 ns1.mango.zw. 86400 IN A 196.29.32.61 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in the parent zone file are often forgotten when changing their A records in the child zone file and keeping their outdated IP addresses in the glue (in the parent zone file) can give you very, very interesting failures.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... el On 2015-12-03 11:10, Mike Silber wrote: > On 03/12/2015 11:03, Dr Eberhard W Lisse wrote: >> Mike, >> >> IPv6 is not an issue :-)-O >> >> Since they don't have DNSSEC EDNS doesn't matter, I think. >> >> ... >> If either telone.co.zw failed to resolve or the data center went >> off line, I don't know what would happen since ns2.gip.net does not >> know about itself. >> >> Probably failure to resolve ZW. > Thank you my umfundisi (teacher) [...] -- Dr. Eberhard W.
