About DNSSnapshot.com

DNSSnapshot is a free tool that lets you take a snapshot of a domain's DNS records and save them for future reference. This is especially helpful before making DNS changes, so you always have a backup of what the records looked like.

This tool attempts to detect common CNAME records using a list of known subdomains. However, DNS only returns CNAME records for specific queries—not as part of a full domain scan. As a result, this list may not be complete. For full visibility, check your domain’s authoritative DNS zone file.
