Question
Here is the hex dump of a UDP header x0045DF0000580000. The source port number is [source], the destination is [dest], the length of the datagram is [len] bytes and the payload size is [pay] bytes. Answer with base-10 integers.
The DNS name "iso.org.dod" is numerically encoded in SMI as
The length of the BER encoding 04 09 48 65 6C 4C .... is [len] and its data type is [type].
The BER encoding 02040000C738 represents a data type of [type], of length [len] bytes representing [num] in decimal.
Ethel Ethernet has a idea. She wants to shrink the minimum 10BASE5 packet size to 16 bytes. This would result in a net diameter of ?
thank you
