I am attempting to understand this little program that converts a
network byte order 32-bit integer to a dotted quad ip address.
#!/usr/bin/python
# Filename : int2ip.py
MAX_IP = 0xffffffffL
ip = 2130706433
def int2ip(l):
if MAX_IP < l < 0:
raise TypeError, "expected int between 0 and %d inclusive" %
MAX_IP
return '%d.%d.%d.%d' % (l>>24 & 255, l>>16 & 255, l>>8 & 255, l &
255)
result = int2ip(ip)
print result
I don't understand the l>>24 & 255.
from the docs;
Right Shift a >> b rshift(a, b)
Bitwise And a & b and_(a, b)
thanks
