Does setting the refresh time in an SOA record make newly created DNS records "propagate" faster? (I understand the term propagate is technically inaccurate)
I'm making many new DNS records (A records to assign subdomains to each new user on the site), and I'd like for that subdomain to be available ASAP after a user signs up. So I'm looking for ways to speed up the rate at which DNS servers check for new DNS records.
Is this possible with the refresh time in the SOA? Or somewhere else?
