You can directly use ip to resolve dns domain names,But because it is a free domain I can not add a level of domain name txt parsing
Another Vercel account is using this domain. Set the following TXT record on _vercel.dpdns.org to use qexo.liziblog.dpdns.org in this project. Once the verification is completed and the domain is successfully configured, the TXT record can be removed.
