ISC software is free, but that certainly doesn’t mean it is costless. From time to time we step back and review the value of our free software.
An article by the Linux Foundation defined a methodology for determining that value. Like most software valuations, it is based on the COCOMO model originally created to quantify the cost of aerospace software.
Using the COCOMO-II model currently published by the University of Southern California, we carefully entered data from all of our BIND 9, BIND 10, and DHCP development. As a result, we have contributed more than $68,000,000 in software and engineering hours to the internet community, looking to build a faster, more secure and reliable Internet. The number didn’t surprise us — we’ve always known the value of BIND — but if you had not thought about the value of free software you might have been surprised.
