@e.mccormick I know the format is like writing a letter.
it has IP header fields, to, from and TTL but i dont know what are the differences.

Well, a letter can be of any length.  Just put more postage on the envelop and get a bigger one.  A envelope has more than one way an address can be written and put on it.  How would you do those for an IP packet?

@e.mccormick  "The IP "envelope" is referred to as a packet or a datagram"?
