« on: April 04, 2021, 03:51:12 AM »
Hello, ive got everything to seem to work fine for right now, but when i try to set a srv record for a clients minecraft server it doesnt show up in dns lookup anywhere no matter what i do. can anyone show me the correct way to set this up.

Code: [Select]
minecraft 60 IN A 51.195.188.144
_minecraft._tcp.play.  IN SRV 0 5 80 minecraft.elementia.tk.


dns result (using the servers own dns via keycdn)
Code: [Select]
; <<>> DiG 9.16.1-Ubuntu <<>> +additional play.elementia.tk @135.148.88.186

1)  You are looking up a "A" record via DIG.  to look up SRV records, you use "dig SRV (domain)"
2)  play.elementia.tk is a NX domain, becasue it has no A record
3)  because you ended play with a period, Bind does not attack the rest of the domain name.  By RFC, any domain ending with a . is considered absolute.  So I'm honestly suprised your not getting an Error of an out of zone domain name.  The following line should work correctly.

_minecraft._tcp.play  IN SRV 0 5 80 minecraft.elementia.tk.
or
_minecraft._tcp.play.elementia.tk.  IN SRV 0 5 80 minecraft.elementia.tk.

Finally, the best way to check a SRV recrod is using the "Host command"

host -t SRV _minecraft._tcp.play.elementia.tk
