If you're managing NS (Nameserver) Hosting, you need to log in to your DNS provider to edit MX and TXT records for your domain.

Log In to Your NS Hosting Account

Find Your NS Hosting Provider

Before logging in, determine which NS hosting service is managing your DNS records.

Run this command in the terminal:

dig NS yourdomain.com +short

Example Output:

ns1.dnsprovider.com
ns2.dnsprovider.com

This tells you which DNS provider to log into (e.g., Cloudflare, Namecheap, GoDaddy, etc.).

Log In to Your NS Hosting Provider

• Visit the DNS provider’s login page.
• Enter your username and password.
• Navigate to "DNS Management" or "DNS Settings".

Example NS Hosting Login Pages:

• Cloudflare: https://dash.cloudflare.com/
• GoDaddy: https://www.godaddy.com/
• Namecheap: https://www.namecheap.com/myaccount/login/
• cPanel DNS: https://yourdomain.com/cpanel

Add or Modify an MX Record (For Email Routing)

MX (Mail Exchange) records route emails to the correct mail server[citation:3].

Locate MX Records in DNS Settings

Once logged in:

• Go to DNS Settings or DNS Management.
• Look for MX Records.

Add or Edit an MX Record

To set up Gmail, Zoho, or a custom mail server, add the correct MX record.

Example MX Records for Google Workspace (Gmail)

How to Add the MX Record

• Click "Add New Record" > Select MX Record.
• Enter:
  • Host/Hostname: @
  • Type: MX
  • Value/Points to/Address: ASPMX.L.GOOGLE.COM
  • Priority: 1
  • TTL: 3600 (1 hour)[citation:1]
• Click Save.

Now, email traffic is routed through the correct mail server.

Add or Modify a TXT Record (For SPF, DKIM, and DMARC)

TXT records store additional domain information, such as SPF, DKIM, and DMARC, which help authenticate emails and prevent spam[citation:5][citation:10].

Locate TXT Records in DNS Settings

• Go to DNS Settings.
• Look for TXT Records.

Add an SPF TXT Record (For Email Authentication)

SPF records prevent spammers from using your domain for email spoofing[citation:4].

Example SPF Record for Google Workspace:

v=spf1 include:_spf.google.com ~all

How to Add the SPF Record

• Click "Add New Record" > Select TXT Record.
• Enter:
  • Host/Hostname: @[citation:1][citation:7]
  • Type: TXT
  • Value/Text/Content: v=spf1 include:_spf.google.com ~all
  • TTL: 3600[citation:1]
• Click Save.

Add a DKIM TXT Record (For Email Encryption)

DKIM signs outgoing emails to verify authenticity[citation:5][citation:10].

Example DKIM Record:

default._domainkey.yourdomain.com TXT "v=DKIM1; k=rsa; p=MIGfMA0GC..."

How to Add the DKIM Record

• Click "Add New Record" > Select TXT Record.
• Enter:
  • Host/Hostname: default._domainkey (or the selector provided by your email service)[citation:4]
  • Type: TXT
  • Value: v=DKIM1; k=rsa; p=MIGfMA0GC... (the full key)
  • TTL: 3600
• Click Save.

Add a DMARC TXT Record (For Anti-Spoofing)

DMARC protects against phishing and email fraud by defining a policy for handling emails that fail SPF or DKIM checks[citation:5][citation:10].

Example DMARC Record:

v=DMARC1; p=none; rua=mailto:reports@yourdomain.com

How to Add the DMARC Record

• Click "Add New Record" > Select TXT Record.
• Enter:
  • Host/Hostname: _dmarc[citation:5]
  • Type: TXT
  • Value: v=DMARC1; p=none; rua=mailto:reports@yourdomain.com
  • TTL: 3600
• Click Save.

Now your domain is secured against email spoofing!

Verify MX and TXT Records

After adding records, verify that they are propagated correctly.

Check MX Records

Run:

dig MX yourdomain.com +short

Expected Output (Example for Gmail MX Records):

1 ASPMX.L.GOOGLE.COM.
5 ALT1.ASPMX.L.GOOGLE.COM.

Check TXT Records

Run:

dig TXT yourdomain.com +short

Expected Output (Example for SPF):

"v=spf1 include:_spf.google.com ~all"

Or use an online tool:

• Google Admin Toolbox MX Checker > https://toolbox.googleapps.com/apps/checkmx/
• WhatsMyDNS > https://www.whatsmydns.net/[citation:3]

Now your NS hosting is set up for email and security!
