How can i find the ips in network in python

How can i find the TCP ips in network with the ra开发者_JAVA百科nge(i.e 132.32.0.3 to 132.32.0.44) through python programming and also want to know the which ips are alive and which are dead. please send me.. thanks for the repliers...

Part 1 - "Finding IPs"

Your example range, 132.32.0.3 to 132.32.0.44 doesn't match any subnet, which is curious.

Typically applications for checking whether hosts are up and down are normally scoped within a subnet, e.g. 192.168.0.0/28 (host addresses: 192.168.0.1 to 192.168.0.14).

If you wanted to calculate the addresses within a subnet, I'd suggest you use ipaddr. E.g.:

>>> from ipaddr import IPv4Address, IPNetwork
>>> for a in IPNetwork('192.168.0.0/28').iterhosts():
...   print a
...
192.168.0.1
192.168.0.2
192.168.0.3
192.168.0.4
192.168.0.5
192.168.0.6
192.168.0.7
192.168.0.8
192.168.0.9
192.168.0.10
192.168.0.11
192.168.0.12
192.168.0.13
192.168.0.14

However, if you're sure that you want an arbitrary range. You can convert an IPv4 address to an integer, increment and convert back to dotted IP. E.g.:

def aton(a):
  """
  Change dotted ip address to integer
  e.g. '192.168.0.1' -> 3232235521L
  """
  return reduce(lambda x,y: (x<<8) + y, [ int(x) for x in a.split('.') ])

def ntoa(n):
  """
  Change an integer to a dotted ip address.
  e.g. 3232235522L -> '192.168.0.2'
  """
  return "%d.%d.%d.%d" % (n >> 24,(n & 0xffffff) >> 16,(n & 0xffff) >> 8,(n & 0xff))

def arbitraryRange(a1,a2):
  """
  Generate all IP addresses between two addresses inclusively
  """
  n1, n2 = aton(a1), aton(a2)
  assert n1 < n2
  i = n1
  while i <= n2:
    yield ntoa(i)
    i += 1

Providing:

>>> for a in arbitraryRange('192.168.0.10','192.168.0.20'):
...   print a
...
192.168.0.10
192.168.0.11
192.168.0.12
192.168.0.13
192.168.0.14
192.168.0.15
192.168.0.16
192.168.0.17
192.168.0.18
192.168.0.19
192.168.0.20

Part 2 - "Alive or Dead"

The question of "alive" or "dead" is complex and entirely dependent on what you mean by those terms. To provide context and contrast, here's a list of testable qualities with regard to an IP address / host:

• Responds to ARP request?
• Responds to ICMP echo request?
• Responds to TCP SYN?
