Suppose I wanted to use ipfw to throttle uploads to youtube. The uploads are made to upload.youtube.com but this domain resolves into multiple different IPs (which also appear to change over time).
Trying to create a rule for the domain results (viewed through
ipfw list) in an entry connected just to the first IP to which the domain resolved to.
How could I get my rule to automatically apply to the domain, with all of its IPs as well as future IPs to which it will resolve to?
