Domains & DNS

Adding a domain

1. Go to Domains → Add Domain
2. Enter the apex domain (e.g. example.com)
3. Choose DNS management: Tundra-managed (PowerDNS) or External (point NS elsewhere)
4. Optionally link to a site

DNS zone editor

Click a domain to open the DNS zone editor. The record table shows all records with:

• Type (A, AAAA, CNAME, MX, TXT, NS, SRV, CAA, DKIM, SPF, DMARC)
• Name, value, TTL
• Lock icon on managed records (created by Tundra — e.g. DKIM keys, ACME challenges)

Adding a record

Click Add Record, fill in type/name/value/TTL, click Save.
Tundra calls the PowerDNS HTTP API; changes propagate within the zone’s SOA serial TTL.

Batch import (DNS templates)

Click Import Template to apply a pre-built DNS configuration:

DNS templates

Tundra ships 30 DNS templates across 5 categories:

Using a template

1. In the DNS zone editor, click Import Template
2. Browse by category or search
3. Select a template — a preview shows all records that will be created
4. Fill in required variables (e.g. {{domain}}, {{ip}}, {{verification_token}})
5. Click Import — records are batch-replaced atomically

Note

Templates marked with ⚠️ Needs extra step require an action outside Tundra (e.g. adding a verification TXT record in Google Search Console).

Domain linking

Link a domain to a site for automatic DNS record creation when the site is provisioned. Go to Domain → Settings → Link to Site.

When linked, Tundra automatically creates and updates the A/AAAA records when the site’s server IP changes.
