Comment:        Zscaler customer traffic originates from colocation facilities around the world. You should *NOT* use the address or contact information here for the purposes of geolocation. Additionally, because traffic egressing our network may belong to any one of our customers, you should not assume that this traffic belongs to us.

What are IP address ranges?

IP address ranges, or netblocks, are groups of related IP addresses. They are usually represented as a base IP address, followed by a slash, and then a netmask which represents how many IP addresses are contained within the netblock. This format is known as CIDR. You'll also sometimes see netblocks given as a start ip address, and an end ip address, or an ip address range.

Traffic works its way around the internet based on the routing table, which contains a list of networks and their associated netblocks.
