1. If an IPv6 datagram with a payload of 1480 bytes and no extension headers must be sent over a network with an MTU of 500 bytes, how many fragments will be sent? Explain.

2. Read RFCs 1149 and 1217. Are they serious network standards? (Hint: consider the dates.)

3. When reassembling fragments, how does IP software know whether incoming fragments belong to the same datagram?
