# DNS Support

[How do I fix the error "Record is managed by an App on this account, and cannot be deleted"?](https://docs.digitalocean.com/support/how-do-i-fix-the-error-record-is-managed-by-an-app-on-this-account-and-cannot-be-deleted/index.html.md): Use the app’s Settings tab to remove domains associated with App Platform apps.

[Why aren't my vanity DNS name servers resolving?](https://docs.digitalocean.com/support/why-arent-my-vanity-dns-name-servers-resolving/index.html.md): If you use vanity or branded DNS nameservers that delegate to DigitalOcean’s nameservers, you must update to new IP addresses.

[How do I fix the DNS error "Primary Name Server Not Listed at Parent"?](https://docs.digitalocean.com/support/how-do-i-fix-the-dns-error-primary-name-server-not-listed-at-parent/index.html.md): Update your registrar to use DigitalOcean’s name servers.

[How do I add an A record to my app on App Platform?](https://docs.digitalocean.com/support/how-do-i-add-an-a-record-to-my-app-on-app-platform/index.html.md): App Platform provides two static ingress IPs you can use to map A records to your app.

[Does DigitalOcean support DNSSEC?](https://docs.digitalocean.com/support/does-digitalocean-support-dnssec/index.html.md): No, we do not support DNSSEC.

[Can I import a DNS zone?](https://docs.digitalocean.com/support/can-i-import-a-dns-zone/index.html.md): You cannot import a DNS zone, but you can add the domain and manually create the DNS records.

[Why does my domain fail to resolve?](https://docs.digitalocean.com/support/why-does-my-domain-fail-to-resolve/index.html.md): A domain could fail to resolve because the name server changes did not completely propagate, `DNSSEC` or the domain registrar needs verification, the DigitalOcean name servers are not configured at your registrar, or there are different name server providers active.

[How do I add a domain that contains special characters?](https://docs.digitalocean.com/support/how-do-i-add-a-domain-that-contains-special-characters/index.html.md): Use Punycode to add a non-ASCII domain name to DigitalOcean.

[How do I transfer a domain between teams?](https://docs.digitalocean.com/support/how-do-i-transfer-a-domain-between-teams/index.html.md): We do not support directly transferring domain ownership from one team to another. Instead, you can download a zone file with all of the domain’s DNS information.
