SRV解析
初步介绍
作用
使用SRV解析可以让Minecraft服务器的域名更加美观，但并不能防止黑客找到服务器IP和端口攻击服务器
- 示例：解析到域名
- 示例：解析到IPV4
这是一条SRV记录，Java版玩家可在地址中输入nekoserver.xyz来访问cserver191279.nekoserver.xyz:25565加入多人游戏。
_minecraft._tcp.nekoserver.xyz. 600 IN SRV 0 10 25565 mcserver191279.nekoserver.xyz.
_minecraft服务Server_tcp协议Protosucixr.cn域名Domain600类ClassINSRV0优先级5权重25565端口mcserver191279.nekoserver.xyz目标（目标可设为A、AAAA或域名，但目标域名也必须指向的也是A、AAAA）
这是一条SRV记录，Java版玩家可在地址中输入sucixr.cn来访问106.15.95.104:49375加入多人游戏。
_minecraft._tcp.sucixr.cn. 600 IN SRV 0 5 49375 106.15.95.104.
查询Minecraft的SRV的记录
- ITDog网页查询
- dig命令
- nslookup命令
比如要查询ngz6.zaku.ltd的Minecraft SRV记录，那就在前面加上_minecraft._tcp.，变成minecraft._tcp.ngz6.zaku.ltd
- 查询
furtherblock.fun的Minecraft SRV记录
$ dig SRV _minecraft._tcp.furtherblock.fun
; <<>> DiG 9.20.10 <<>> SRV _minecraft._tcp.furtherblock.fun
;; global options: +cmd
;; Got answer:

可以发现
furtherblock.fun指向了域名30c446fc.mcsm.top端口30414
- 查询
30c446fc.mcsm.top的DNS记录
$ dig 30c446fc.mcsm.top

这里可以看到
30c446fc.mcsm.top解析了两个地址
- 一个CNAME解析，解析到了域名
gbefcd6.cdn.mcsm.top- 一个A到了
104.233.189.36
查询gbefcd6.cdn.mcsm.top地址
$ dig gbefcd6.cdn.mcsm.top
