DNS records let you control how traffic reaches your subdomain. From the dashboard you can add any supported record type, set a custom TTL, enable Cloudflare proxying for eligible records, and delete records you no longer need — all without touching a registrar or zone editor.

​
Getting to the Records page

Navigate to Dashboard → Domains, select your subdomain, then click Records in the subdomain navigation.

​
Creating a record

1

Open the Create DNS record form

At the top of the Records page you will see the Create DNS record card. The form shows the fields relevant to the record type you select.
2

Choose a record type

Use the Type dropdown to select one of the supported types: A, AAAA, CNAME, TXT, MX, or SRV. The form fields update automatically to match the chosen type.
3

Set the Host

Enter a value in the Host field.
  • Use @ (the default) to target the subdomain itself — for example, alice.nxtdev.xyz.
  • Enter a relative name to create a sub-host. For example, entering api on alice.nxtdev.xyz creates api.alice.nxtdev.xyz.
Host labels must be lowercase alphanumeric and may contain ., _, and -. Labels cannot start or end with . and are capped at 63 characters.
4

Fill in the record-specific fields

Provide the Content (or Target for SRV records) and any additional fields such as Priority, Weight, or Port. See Record Types for the full field reference per type.
5

Set the TTL

Enter a TTL (time-to-live) in seconds. The minimum is 60, the maximum is 86400, and the default is 3600. A lower TTL means resolvers re-query more frequently; a higher TTL reduces query volume but slows down propagation of future changes.
6

Enable proxying (optional)

For A, AAAA, and CNAME records, a Proxied (Cloudflare) checkbox appears. When checked, traffic routes through the Cloudflare proxy network instead of resolving directly to your origin. Proxying is not available for TXT, MX, SRV, or NS records.
7

Submit the form

Click Create record. The new record appears in the Records table below.

​
Editing and deleting records

Each row in the Records table has two action buttons:
  • Edit — opens the record’s edit page where you can update any field.
  • Delete — permanently removes the record. The button is disabled while delegation is enabled or the subdomain is suspended.

​
Limitations and blocked states

When NS delegation is enabled for your subdomain, the DNS editing form is hidden and all records become read-only. To make changes, go to Nameserver Settings and remove the delegation first.
If your subdomain is suspended, DNS changes are blocked until the suspension is lifted. The Delete button is also disabled in this state.
