• what does "dead beef" mean?

  - by Xi

  Hi there: What does the word "dead beef" mean? I read it from a interview question. It has something to do with ipv6. I figured it could be a random hex number used for examples, like "The quick brown fox jumps over the lazy dog". Is my understanding correct? Or it has more significant meaning? Thanks!

• Port forwarding in C#/software possible? Isn't it only managed by the router?

  - by Rudi

  Isn't port forwarding managed by the router? Like, I've googled up some software applications that seem to port forward with great success, but it technically seems to be impossible. The packet must first go to the router. The router must forward it to the correct computer based on port forwarding rules. So how can a software application manage port forwarding if the packet must GO to the computer running this software application in the first place, meaning that port forwarding already is successful in the first place?
