DNS configuration

Hi Vercel Support Team,

I am writing to request a manual verification for the domain smid.snu.ac.kr.

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 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 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 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 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._
