Firebase托管绑定.com.bd自定义域名：无TXT记录入口求解决方法

Great question! Since your .com.bd domain only lets you modify primary/secondary/tertiary DNS servers (and not individual records like TXT or CNAME), you have two reliable workarounds to get it connected to Firebase Hosting:

Option 1: Use Cloudflare as an Intermediate DNS Provider #

This is the most common and straightforward fix for this scenario:

• Sign up for a free Cloudflare account and add your .com.bd domain to it. Cloudflare will generate a set of authoritative DNS server addresses for you.
• Head back to your domain registrar's dashboard, replace all existing primary/secondary/tertiary DNS servers with the ones provided by Cloudflare.
• Wait for DNS propagation to complete (this can take anywhere from 1-24 hours, depending on global DNS cache times).
• Once propagation is done, go to Cloudflare's DNS tab for your domain, and add the exact TXT record (for domain verification) and CNAME record (for hosting routing) that Firebase Hosting provides in its setup wizard.
• Pro tip: If you run into routing issues, make sure the CNAME record is set to DNS Only (grey cloud icon) instead of proxied (orange cloud) — this ensures traffic flows directly to Firebase's servers without Cloudflare's proxy interfering.

Option 2: Migrate to a Registrar That Supports Individual Record Edits #

If you'd prefer not to use a third-party DNS provider, consider transferring your .com.bd domain to a registrar that lets you manage individual DNS records (like TXT/CNAME). While this involves a transfer process (which can take a few days), it gives you direct control over all settings needed for Firebase Hosting. Just be sure to check the specific transfer rules for .com.bd domains first (country-code TLDs often have unique requirements).

Important Notes #

• Before switching DNS servers, make sure to note down any existing critical DNS records (like MX records for email, or A records for other services) — you'll need to re-add these in your new DNS provider (Cloudflare, or your new registrar) to avoid service outages.
• DNS propagation can take longer for .com.bd domains in some regions, so be patient. Use tools like nslookup or dig to verify that the new DNS servers are active before proceeding with Firebase's verification step.
