Class Method Details

.get_front_ip(request = nil) ⇒ Object

##

Get the front IP — DNS resolution of the request host. Represents the public IPv4 that browsers reach (reverse proxy like Caddy/Nginx, CDN, load balancer…) before traffic hits the application server.

Uses explicit Google/Cloudflare nameservers with a 2s timeout per server (so up to ~4s total in worst case) to avoid hangs when the system resolver is misconfigured. Filters to IPv4 only for consistency with the other IP helpers in this module.

Returns nil if request is missing, host is empty or no IPv4 record is resolved.
