Abstract

Giving a hostname to your computer and publishing it as you roam fromone network to another is the Internet's equivalent of walking aroundwith a name tag affixed to your lapel. This current practice cansignificantly compromise your privacy, and something should change inorder to mitigate these privacy threats.

There are several possible remedies, such as fixing a variety ofprotocols or avoiding disclosing a hostname at all. This documentdescribes some of the protocols that reveal hostnames today andsketches another possible remedy, which is to replace statichostnames by frequently changing randomized values.
