🌐 DNS Zone Configuration in ISPmanager

When adding a domain in ISPmanager, it's important to configure the DNS zone correctly so your website, email, and other services work reliably. ISPmanager lets you manage all types of DNS records: A, AAAA, MX, TXT, CNAME, and more. In this article, you'll learn how to create DNS records, connect a domain, configure email, and verify everything works. 📡

📁 What Is a DNS Zone?

A DNS zone is a set of records that tells the internet how to route traffic for your domain: where the website is hosted, where the email server is, what servers can send email, etc. Without proper configuration, your domain may not work or behave inconsistently.

🔧 How to Add a Domain and DNS Zone

• 1️⃣ Go to ISPmanager → “Domain Names”;
• 2️⃣ Click “Create” and enter your domain name;
• 3️⃣ Enable the “Create DNS zone” option — this will generate a basic template;
• 4️⃣ After saving, you can edit the zone and add records manually.

📌 Types of DNS Records

• 🔷 A record — links your domain to an IP address (e.g., 1.2.3.4);
• 🔷 CNAME — alias (subdomain → main domain);
• 🔷 MX — mail servers for the domain (e.g., mail.yourdomain.com);
• 🔷 TXT — technical info like SPF, DKIM, domain verification;
• 🔷 AAAA — IPv6 address (if used);
• 🔷 NS — nameservers, if you're managing DNS directly.

📬 Email Configuration (MX and SPF)

If you're using a built-in or external email provider (e.g., Yandex 360, Google Workspace), you need to set up:

• 📮 MX record with priority 10 pointing to your mail server;
• 🔒 TXT record for SPF to authorize sending (e.g., "v=spf1 +a +mx -all");
• 🔑 DKIM records — can be generated in the panel or added manually.

🔍 Verifying DNS Functionality

After creating or updating records, check them using public DNS tools such as Google Dig or MXToolbox. Keep in mind that full DNS propagation may take up to 24 hours.

🧠 Tips from Bit.Hosting

• 🗂 Avoid creating unnecessary records — keep your zone clean;
• 📛 Do not mix A and CNAME records for the same subdomain;
• 📅 Only change TTL when needed;
• 🔄 Backup DNS zones before making major changes.
