Proposed Standard for the Transmission of IP Datagrams over FDDI Networks
RFC 1188

RFC 1188              IP and ARP on FDDI Networks           October 1990

Appendix on Numbers

   The IEEE specifies numbers as bit strings with the least significant
   bit first, or bit-wise little-endian order.  The Internet protocols
   are documented in bit-wise big-endian order.  This may cause some
   confusion about the proper values to use for numbers.  Here are the
   conversions for some numbers of interest.
