That value is the id of the next protocol header right after Ethernet. The Ip4 header has a reserved id value of 0x800 for it. So anyone reading that packet has to look into that type field in order to determine the next protocol. When he does, 0x800 in that field tells him the next header is Ip4.
1 The Constitution contains no reference to any right to privacy. 2  However, over more than 100 years, courts have found a fundamental (but somewhat vague) right to privacy implicit in the Constitution.
Privacy is sometimes related to anonymity although it is often most highly valued by people who are publicly known. Privacy can also be seen as an aspect of securityâone in which there are trade-offs between the interests of one group and another can become particularly clear.It is a comprehensive right and it is the right most valued by a free people. It is a fundamental human right. A society in whish there was a total lack of privacy would be intolerable; but then again a society in which there was a total privacy would be no society at allâ (the is a balance needed).
