Minecraft DNS SRV record correct setup
Solution 1:
The SRV record should be created for _minecraft._tcp.mine.rlnd.cz
, not _minecraft._tcp.rlnd.cz
.
More Info:
SRV records are not always directly under the domain name - _service._proto.domain.com
.
I think this may be a fairly common misconception with SRV, partly because the poster-child application for it, Exchange/Outlook, uses the domain portion of your email address and a lot of information online generally tells you that 'you need an SRV record for your domain'.
If you enter a.b.domain.com
into an SRV aware application, it will lookup the SRV record for _service._proto.a.b.domain.com
