This counter tracks DHCPINFORM packets received, sent by clients that already have an IP address (often configured statically) but want additional configuration parameters like DNS servers or domain name from this server without requesting a lease. A nonzero count here indicates devices on the network are using this DHCP server purely as a configuration source rather than for address assignment, which is useful for an admin auditing exactly how many statically-addressed hosts still depend on this server. For example, print servers with fixed IPs might send Informs just to pick up the current DNS server list from cigDhcpServersPoolDnsServer.
