Your panel's website address affects how customers recognize and revisit it. An included subdomain and a custom domain can both open the same kind of client website, but their setup and ownership are different. Choose based on the business identity you need and the configuration you are prepared to manage.
The included subdomain option
An included Delix Panels subdomain uses an available name followed by delixpanel.com. The platform manages the shared hosting arrangement. A renter should not need to add an individual registrar DNS record for every included subdomain.
This can make the first launch simpler because there is no separate domain purchase. You still need to check that the chosen address opens the correct panel and that customer navigation works after the rental is activated. An active subscription and a reachable website are related but distinct checks.
The custom-domain option
A custom domain is an address you register and renew separately. It can provide a website identity that does not include the rental platform's domain. You retain responsibility for renewal and for following the connection instructions in the domain settings.
Buying a domain does not automatically connect it to a panel. DNS records or nameserver changes, hosting verification and HTTPS readiness all need to line up. Follow the values displayed for your domain; do not copy challenge records from someone else's setup.
Preserve other services on the domain
Before changing nameservers, make a record of the existing website, email and verification entries. A domain may support more than the panel homepage. Losing an email record can interrupt mail even when the new website loads correctly.
Ask for support when you do not know which records must be preserved. Keep the registrar account secure and avoid sharing its password with customers. The goal is a working domain connection, not a wholesale replacement of unrelated services.
Understand activation without guessing
DNS resolvers can temporarily show different answers after a change. However, repeated failures are not automatically normal propagation. A missing record, an incorrect target, a conflicting hosting attachment or a DNS-provider fault can each require a different repair.
Check the status shown by the panel, then verify the actual website using HTTPS. Make sure it displays your own brand and account flow. Repeatedly paying for a second panel does not resolve a domain configuration fault.
Make the change with a fallback
Keep an already-working included address available while you finish setup. Once the custom address is secure, test registration, sign-in and payment-return navigation there. Update the links you publish only after those checks succeed.
For a first launch, the subdomain is often the simpler operational choice. A custom domain is useful when a separate brand address matters and you are ready to maintain it. Neither option removes the need to test the customer journey and keep domain-related accounts under your control.
