Comment # 7 on bug 11861 from 
The bit labelled 0 is the high order or most significant bit.

A reading of RFC 791 Appendix B should help clear up any confusion.

>From https://tools.ietf.org/html/rfc791#page-39:

Whenever an octet represents a numeric quantity the left most bit in the
diagram is the high order or most significant bit.  That is, the bit
labeled 0 is the most significant bit.  For example, the following
diagram represents the value 170 (decimal).


                            0 1 2 3 4 5 6 7
                           +-+-+-+-+-+-+-+-+
                           |1 0 1 0 1 0 1 0|
                           +-+-+-+-+-+-+-+-+
