I'm trying to get my minecraft server to be reachable through my domain name, as opposed to needing to connect with the IP and port. Because I want to host multiple servers, it would be ideal if I could tie a subdomain to a port, so then people could just connect to minecraft.sandwich247.com and be in to the main server, or somethingelse.sandwich247.com to go to a different server.

On my dns provider's website, I've created an A record with

Domain Target
minecraft 77.99.72.13

I've created an SRV record with the server of

Domain _minecraft._tcp.minecraft.sandwich247.com

Target minecraft.sandwich247.com

Priority 0

Weighting 5

Port
25565

 

In minecraft, if I try to connect to 77.99.72.13:65535, it works fine.

If I try to connect to minecraft.sandwich247.com it does not

Running nslookup minecraft.sandwich247.com gives

Server:  194.168.4.100
Address: 194.168.4.100#53

Non-authoritative answer:

Name:    minecraft.sandwich247.com
Address: 77.88.72.13

If I run nslookup -type=SRV _minecraft._tcp.sandwich247.com then I get

Sever:   192.168.4.100
Address: 194.168.4.100#53

Non-authoritative answer:
_minecraft._tcp.sandwich247.com service = 0 5 25565 minecraft.sandwich247.com

Authoritative answers can be found from:
minecraft.sandwich247.com internet address = 77.99.72.13

If I run nslookup -type=SRV _minecraft._tcp.minecraft.sandwich247.com then I get

Server: 194.168.4.100
Address: 194.168.4.100#53

** server can't find _minecraft._tcp.minecraft.sandwich247.com: NXDOMAIN

I have no idea what that 194.168.4.100 IP address is (possibly my ISP?)

If I use a port checker to see if minecraft.sandwich247.com has port 25565 open, then it says it's closed, but checking with the IP says it's open.

 

Is what I'm trying to do possible? What am I doing wrong?

Thanks

  • 194.168.4.100 is a Virgin Media Public IP, somewhere in London. So is 77.99.72.13 – Tetsujin Dec 30 '21 at 15:03

    In fact 194.168.4.100 is Virgin's default DNS address – Tetsujin Dec 30 '21 at 15:06
  • Very strange, do you think I need to contact them to get this sorted? – Sandwich247 Dec 30 '21 at 15:31
  • I honestly don't know - the address looked familiar but I couldn't remember why, so i went to look it up. It was only a few minutes later I realised why I knew it … I'm on Virgin too ;) – Tetsujin Dec 30 '21 at 15:42
  • There is really only one possibility: you actually did _not_ create the DNS record you think you created. Check your SRV record again. – Daniel B Dec 30 '21 at 17:24
  • see, that's what I was thinking, but I've quadruple quintuple checked and I *think* it's okay? https://i.imgur.com/ywH8EZy.png https://i.imgur.com/MPVbIUj.png – Sandwich247 Dec 30 '21 at 17:53
  • It’s not. The entry is/was for `_minecraft._tcp`, not `_minecraft._tcp.minecraft`. – Daniel B Dec 30 '21 at 20:05

RIGHT!

I did everything correctly, it's just my IP had changed from ending in 13 to ending in 12 :facepalm:

Looks like I need to double check the cron job I have set which calls the API for my DNS Provider which should be automatically updating the IP address it links to :/
