From our mirror checking host:

From my home machine:

iPanic:Music ralph$ host -a mirror.lihnidos.org Trying "mirror.lihnidos.org" ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 27295 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 0

Yet I am able to reach your mirror with my browser, but (again from my home machine):

Thank you for your in-depth analyze

iPanic:Music ralph$ curl http://mirror.lihnidos.org/CentOS/timestamp.txt curl: (6) Couldn't resolve host 'mirror.lihnidos.org'

iPanic:Music ralph$

...

Does anybody know why this happens? IPv6 firewall is configured to allow HTTP trafic.

Looks like I only get the AAAA address. Home machine is OS X, mirror checker is CentOS.

You were right. I did only have AAAA record for mirror.lihnidos.org and A record for *.lihnidos.org. And because absolute A/AAAA entries override scaron entries (*), DNS system was only returning AAAA record. I have added A record now, so it should work normally now.

Thank you and best regards, Damjan Sirnik
