What happens if you change it, and cause a conflict with another ISP customer?
Some ISPs that do dynamic addressing hash the MAC address to derive IP address.

BTW, posting your email address openly will get you more unwanted email, than
wanted email. Learn to munge your email address properly, to keep yourself a

internet - read this article.
