Questions
• TCP/IP not designed for security. Are they
vulnerable? How? Can we fix it?
• I heard about IP addresses and routers, but
don’t know how they work.
• Where does error checking take place?
Motivated by failed downloads.
• How are IP addresses allocated? Reliability at
the bit transmission level?
