Test, validate and match regular expressions
This PCRE2 regex matches domain names used by the ESET Push Notification Service (EPNS). It captures base domains like 'epns.eset.com' as well as broker-specific subdomains such as 'h1-epnsbroker01.eset.com' by utilizing a conditional check. It is highly useful for network monitoring, DNS filtering, and log analysis to track ESET endpoint communications.
