Did you check both IPv6 and IPv4 clients?

Only if they reach Squid as identifiably different IPs.

It is the count of distinct IPs currently in the client-DB.

The client-DB is the set fo distinct IPs connected to your Squid from
any direction (both LAN and WAN) over a period of up to 24hrs. They are
"faded" / aged out of the DB dynamically based on several factors
including last access and frequecy of access when the client-DB garbage
collector gets run to remove old entries.
