Cloud DNS
DNS determines which server, application or email service your domain points to. With Deplomo DNS, you can add a domain, change nameservers at your domain registrar and create records such as A, AAAA, CNAME, MX and TXT. Before changing important records, note their current values and set TTL according to the sensitivity of the change. Browser, operating system and ISP caches mean users may not all see the new value at the same time.
Key points before configuring DNS
DNS is separate from domain registration
Deplomo hosts the zone and its records. Domain ownership, renewal and nameserver changes still take place through your domain registrar.
Record updates in Deplomo DNS
After you save a record in the dashboard, the change is applied to Deplomo nameservers. Query those nameservers directly to check the new value without interference from local caching.
Internet propagation time
Even when a record changes quickly in Deplomo, public resolvers, ISPs and users’ devices may retain the old value until its TTL expires. For sensitive migrations, lower TTL several hours beforehand and increase it again after the service stabilizes.
Common DNS records
A and AAAA records
Connect a domain or subdomain to an IPv4 or IPv6 address. Enter the destination service’s IP address exactly.
CNAME records
Point a subdomain to another domain name. For the root domain, A/AAAA records or provider-specific settings are usually used.
MX records
MX records identify the servers that receive email for your domain. If you use a hosted email service, configure each MX record with the priority specified by that provider.
SPF, DKIM and DMARC
SPF records are TXT records that list the servers authorized to send email for your domain. DKIM signatures and DMARC policies add further email authentication controls; follow the values supplied by your email provider.
TXT records
Used for email, domain ownership verification, SPF, DKIM and DMARC. Preserve quotes and spaces when entering TXT values.
TTL settings
TTL determines how long a record stays cached. Low TTL suits migrations; a higher TTL reduces query volume once the service is stable.
Connect a domain to Deplomo DNS
Add the domain in the dashboard
Enter the domain without http, https or a path. If it already has active records, export or note those records before moving it.
Change the nameservers
Replace the nameservers at your domain registrar with those displayed in the Deplomo dashboard. This can take time depending on the registrar and internet caches.
Create the required records
Create the A, CNAME, MX and TXT records needed by your web and email services. Check each record’s name, type, value and TTL individually.
Check propagation
Use dig or similar tools to query the Deplomo nameserver directly, then public resolvers, to distinguish cached responses from the authoritative value.
Useful commands
Check the server IP address (A record)
Use dig to query DNS and check which public IPv4 address your domain currently resolves to.
dig A example.com +shortCheck mail routing (MX record)
Use this command to check which mail servers receive email for your domain.
dig MX example.com +shortCheck the domain’s active nameservers (NS record)
Use this command to check which nameservers the domain currently uses. Compare the result with the nameservers shown in your Deplomo dashboard.
dig NS example.com +shortCheck TXT records, including SPF
Use this command to inspect the domain’s TXT records, including SPF.
dig TXT example.com +shortQuery the Deplomo server directly without local caching
If your ISP has cached old information, this command sends the query directly to the Deplomo authoritative server. It shows the latest recorded values without relying on the local cache.
