It's enumeration through 32 bits of 0-4294967295. There are only so much IPv4 addresses.
If you add a salt, then that "net location ID" becomes of very limited use. You won't be able to grep through the logs for request from specific IP, you won't be able to tell how many distinct IPs are accessing your services, etc etc. The only use I can see is keeping it in the session to check if IP address had changed, as a security measure.
