I am currently unable to add this domain because your system insists on a TXT record at the root domain (\_vercel.snu.ac.kr). However, please understand the following context: University Domain Policy: [snu.ac.kr](https://snu.ac.kr) is the root domain of Seoul National University. As a researcher/lab member, I have no administrative privileges to modify the root DNS records of the entire university. Subdomain Ownership Verified: I have full control over the [smid.snu.ac.kr](https://smid.snu.ac.kr) subdomain. Following the standard protocol for subdomains, I have already added the required TXT verification record to the specific host: \_vercel.smid.snu.ac.kr. Live Record Confirmation: You can verify this record right now via any public DNS resolver (e.g., Google 8.8.8.8): Host: \_vercel.smid.snu.ac.kr Type: TXT Value: (as shown in my project) It seems your automated system is blocking this due to a “domain linked to another account” error or a strict policy on public suffixes. Since I have provided clear proof of ownership at the subdomain level, please manually bypass this restriction and link [smid.snu.ac.kr](https://smid.snu.ac.kr) to my account. I look forward to your prompt resolution. and below is the answer from automated web support system. Thank you for the detailed explanation! I completely understand the situation — as a researcher at Seoul National University, you don't have access to modify the root domain's DNS records, but you do have control over your subdomain `smid.snu.ac.kr`. Let me analyze your domain to see what's happening and check if we can help resolve this. I can see from the domain analysis that your subdomain `smid.snu.ac.kr` is actually already pointing to Vercel (using Vercel nameservers), but there's a `DEPLOYMENT_NOT_FOUND` error — which suggests the domain hasn't been fully linked to a project yet. I understand your situation clearly: * **[snu.ac.kr](https://snu.ac.kr)** is a public suffix (university root domain) that you cannot control * You've correctly added the TXT record at `_vercel.smid.snu.ac.kr` to prove subdomain ownership * Vercel's system is asking for verification at the root level, which is impossible in your case This is a known limitation where our automated verification system requires root domain access, but users with delegated subdomains (like university researchers, lab members, or departments) cannot modify root DNS. Since you've already: 1. Added the correct TXT verification record at `_vercel.smid.snu.ac.kr` 2. Configured the subdomain to point to Vercel nameservers This requires manual intervention from our support team to bypass the root domain verification requirement. Let me check if I can create a support case for you. I've prepared a support case for you. A case form should now be visible below this message with your details pre-filled. **Summary of your request:** * Domain requiring manual verification: `smid.snu.ac.kr` * TXT record already configured at: `_vercel.smid.snu.ac.kr` * Request: Bypass root domain verification requirement Please review and submit the case form, and our support team will manually verify your subdomain ownership and help link it to your account.\_
