FIRST and LAST seem like poor choices for words. Do you mean first on the
wire? Network protocols are almost always little endian.
In any case, those masks are not within an ifdef so they will be used in both
If you want the low or high bits, the masks and macros don't depend on the
endianness if you are extracting from a uint64_t. You may need to invent a
new host2net type macro to byte swap an 8 byte chunk if you want to
send/receive those chunks from the network.
These are my opinions. I hate spam.
