Pings a list of IPs/hostnames from inside your network and reports which are unreachable. Use this to check LAN-only or VPN-only devices that the public-internet site1.erralert.com checker cannot reach.

Placeholders only. Before running, replace YOUR_URL with your capture endpoint's POST URL . (Open this page from your capture object to have these auto-filled.)
