But that is a different number :)

https://metacpan.org/pod/perlfunc#pack says 

The integer formats s, S, i, I, l, L, j, and J
...
For example, a 4-byte integer 0x12345678 (305419896 decimal) would be 
+ordered natively (arranged in and handled by the CPU registers) into 
+bytes as

    0x12 0x34 0x56 0x78  # big-endian
    0x78 0x56 0x34 0x12  # little-endian

So I type 

$ perl -V:byteorder
byteorder='1234';

$ perl -e"print 0x12345678 "
305419896

$ perl -e"print unpack q{H*}, pack q{N*}, 0x12345678 "
12345678

$ perl -e"print unpack q{H*}, pack q{N*}, 305419896 "
12345678

$ perl -e"print sprintf q{%x}, 305419896 "
12345678

Which seems to agree with above and  N  An unsigned long (32-bit) in "network" (big-endian) order.

N packs 305419896 correctly as big-endian, and my machine is big endian (as sprintf shows)
