A Web Domain Name or URL is similar to your house Street Address. Its what everyone sees when they search for you. In the example above you see Googles URL (google.com) you don't see the numbers and dots of the IP address. Similarly when someone comes over to your house, they don't look for "Lot 79". They will look for eg. 1 Brisbane St, Brisbane, Australia 4000. Web Domain (URL) = Street Address
