Validate DNS before you deploy VaultSandbox
Start with your server IP, add your domain or subdomain, and we will tell you exactly which DNS records to create and whether they resolve correctly.
Step 1
Enter your server IP
We use this to generate the A record. Use the public IPv4 address of the machine where you will run VaultSandbox.
Paste the public IPv4 of the machine that will receive mail.
Step 2
Choose domain or subdomain
Start with your base domain, then decide if you want to use a subdomain (recommended) or the root. We’ll build the exact host and records for you.
Enter your registered domain (e.g. example.com).
We’ll assemble the full host (e.g. qa.yourdomain.com) and the DNS label for you.
Step 3
Add these DNS records
Paste these into your DNS provider. Update the values first, then run the check below to confirm propagation.
Host/Name shows only the label (e.g. mail). Use @ when pointing the root domain. Values use the full host.
