If you are using Google Analytics for web analytics it can be beneficial to exclude certain addresses to provide a more accurate view of traffic to the site. There are numerous reasons that excluding IP’s from the analytics statistics such as if it is a personal site that doesn’t do a lot of traffic and you are working on all the time from home the analytics results might not provide a real world view of what other visitors view the most. Another example might be if it’s a corporate web site that numerous developers, QA personal, and others employees are visiting from the same address space it could skew the analytics results because of such a high concentration of traffic from one IP address or subnet. One of the great reasons for reviewing the web analytics data provided by Google Analytics is to see what pages customers view or what region your customers are from. This type of data can help prioritize the areas of the site that should be worked on the most or what content provides the best return on investment and if the data includes your own traffic it might not provide accurate data for you to review.

The easiest way to configure a static IP on the HP Photosmart C5100 is via the web interface. You probably do not know to the IP address of the all-in-one printer since you are just now configuring the static IP and if it is currently on the netork then it has received a dynamic IP address via DHCP (Dynamic Host Configuration Protocol). Regardless its an easy process which I will explain step by step below.

1. Locate IP Address: First we will need to locate the current Internet Protocol address of the printer. Look in the properties of the printer and look at the Ports tab to see if there is an IP address specified. If there is not then you can print a test page, bring up a command prompt, and type “arp -a”. You should notice a couple different IP addresses of which one should be associated with a Physical Address that begins with 00:19:BB which is Hewlett Packard.
