The IPv4 or IPv6 addresses in CIDR notation to use for the Suricata <code>HOME_NET</code> variable. If your
firewall uses an inspection VPC, you might want to override the <code>HOME_NET</code> variable with the CIDRs of
your home networks. If you don't override <code>HOME_NET</code> with your own CIDRs, Network Firewall by default
uses the CIDR of your inspection VPC.
