Right now we can block (and delete) browser cookies to stop being tracked across the web sites we visit.  I've noticed recently a significant uptick in specific banner ads on unrelated sites (ie news) for specific products I've browsed at a shopping site like B&H.  This is troubling, and while I deleted my entire cookie cache when I realized it, I'm tempted to institute a per month full cookie delete.

We can't reliably be tracked (or track our own customers, should we wish to) over time by our IPv4 address both because of NATs, and because of DHCP.  I'm not sure I've heard this yet in this discussion thread, but I have this distinct impression that an IPv6 address is more or less static, because it is based on the hardware address of the NIC?  If so, that would negate any efforts to delete tracking cookies.
