What is rlIpDhcpSnoopIPAddress?
This read-write IpAddress records the IP address of the DHCP client referred to by this snooping binding table entry. An admin cares because this is the core piece of information IP Source Guard and anti-spoofing checks rely on to validate that traffic claiming this address is coming from the right place. For example, an admin investigating a spoofed-source-address alert would look up this field in the binding table to confirm which client the switch believes legitimately owns that IP.
