About DnsWarn

DnsWarn is an extension designed to monitor and alert you when the DNS records of the website you are visiting have recently changed. It helps users stay informed about potential updates to DNS information, such as changes to A, CNAME, MX, or other record types, which could indicate configuration updates, migrations, or even potential security issues like DNS hijacking.
