Yes, Private DNS supports wildcard resolution. Wildcard resolution allows for a single DNS record to represent multiple subdomains. For example, if you have a wildcard DNS record for *.example.com, it would match www.example.com, blog.example.com, and any other subdomain under example.com. This is useful for managing large numbers of subdomains without needing to create individual DNS records for each one.
In the context of cloud services, Tencent Cloud's Private DNS offers this capability, allowing users to configure wildcard DNS records to simplify domain management for their applications and services hosted on Tencent Cloud.
