- Sign in to your Dynadot account.
- Go to My Domains → Manage Domains, check the box next to your domain and click Action → DNS Settings.
- At the top of the DNS Settings page choose Dynadot DNS from the dropdown.
- Since your host is a subdomain, under Subdomain Record (optional):
- Subdomain: LONG-STRING-OF-CHARACTERS.yourdomain.com
- Record Type: TXT
- IP Address or Target Host: LONG-STRING-OF-CHARACTERS
- Click Save Settings.
- Wait 3–5 minutes for DNS propagation.
- On the Swwwap verification page click Verify.
Note: Dynadot will not accept a lone TXT record. You must have at least one other root record (A, AAAA, CNAME or forwarding) defined before saving a TXT entry.
