Lose the Port Number! How to Make Your Minecraft Server Domain Professional Like Big Companies (SRV Records Explained)

As a server owner, have you ever experienced such embarrassment:

You: "Come play on my new server! The IP is mc.super-server.com...... oh, by the way, don't forget the port, it's mc.super-server.com:12345."

Player: "I can't connect!"

You: "Did you type the colon as a Chinese character? Did you forget to enter the port?"

This experience is simply terrible. Look at Hypixel, look at NetEase; they only ever need to enter a clean domain name.

Is it because they bought the default 25565 port?
Not necessarily. Many times, it's because they use a DNS technology ignored by 99% of novice server owners —— SRV Records.

What is an SRV Record? (Beginner Version)

Imagine you are sending a package.

• A Record is like the address of a neighborhood: "88 Xingfu Road".
• SRV Record is like a specific room number: "88 Xingfu Road, deliver to the Minecraft Mailroom".

When you configure an SRV record, the player's client quietly asks the DNS server when connecting to mc.yoursite.com: "Hey, is there a Minecraft service here?"
The DNS server answers: "Yes! Please forward to port 12345 of node1.yoursite.com."

All of this is transparent to the player! They only entered the domain name, not the port, but successfully connected.

Why do you need it?

1. Professionalism:

   • ❌ play.mcserver.top:54321 (Looks like a small server that might disappear at any time)
   • ✅ play.mcserver.top (Looks like a thousand-player server)

2. Security:

   • Hide the real backend IP. When combined with reverse proxy cluster servers like BungeeCord or Velocity, SRV is standard.

3. Flexibility:

   • Even if you change server rooms or ports, as long as you modify the DNS record, the domain name in the player's hand never needs to change.

Step-by-Step Configuration Guide (Trap-avoidance Version)

Many tutorials only teach half of it, leading to configuration failures for many. Here are the complete steps:

1. Preparation

Suppose your real IP is 1.1.1.1 and the port is 25577.

2. Set A Record (Backend)

First, create a normal A record pointing to the IP. It's recommended to use an uncommon subdomain.

• Host Record: node1
• Record Value: 1.1.1.1
  (At this point, you can connect via node1.yoursite.com:25577)

3. Set SRV Record (Frontend)

This is the key! Add an SRV record in the DNS console:

• Service: _minecraft (Note the underscore!)
• Protocol: _tcp (Note the underscore!)
• Host Record (Name): play (This is the prefix you want players to enter)
• Weight/Priority: Fill in 0 or 5.
• Port: 25577 (Your real port)
• Target: node1.yoursite.com (Never fill in an IP! You must fill in a domain name!)

Still can't figure it out? Use a generator!

Filling in DNS records manually is most prone to format errors, like missing a dot or adding an extra space.

I've prepared a Minecraft SRV Record Generation Tool for you.
You just need to enter your IP and port, and it will automatically generate:

1. Standard DNS record values
2. Specific filling guides for Alibaba Cloud, Tencent Cloud, and Cloudflare

After configuration, you can also use its one-click detection function to confirm whether the global DNS is effective.
