1.1. addressing - module functions

import addressing module from nettoolkit as below.

Functions of addressing will be available to be used than after.

>>> from nettoolkit.addressing import *

  • There are few addressing functions - which can be used after creating IPv4 or IPv6 Object. These are described in following two pages.

  • There are few addressing functions - which can be used without creating IPv4 or IPv6 Object. These are desscribed as below.

1.1.1. bin_mask()

  • converts and provides binary mask

>>> bin_mask(24)
'255.255.255.0'

1.1.2. to_dec_mask()

  • exactly opposite of above

>>> to_dec_mask("255.255.255.0")
24

1.1.3. bin2dec()

  • decimal number of mask for provided binary mask input

>>> bin2dec('11111111111111111111111111110000')
4294967280

1.1.4. bin2decmask()

  • subnet-mask for provided binary mask input

>>> bin2decmask('11111111111111111111111111110000')
28

1.1.5. binsubnet()

  • binary representation of given subnet

>>> binsubnet('10.10.10.0/24')
'00001010000010100000101000000000'

1.1.6. dec2dotted_ip

  • converts decimal ip address to dotted decimal ip notation

>>> n = 183490304
>>> dec2dotted_ip(n)
'10.239.215.0'

1.1.7. subnet_size_to_mask

  • converts subnet size to get subnet mask value

>>> subnet_size_to_mask(256)
24
>>> subnet_size_to_mask(512)
23

1.1.8. inv_subnet_size_to_mask

  • converts inverse subnet to get subnet mask value

>>> inv_subnet_size_to_mask(255)
24
>>> inv_subnet_size_to_mask(511)
23

1.1.9. get_subnet

  • get subnet/mask from decimal network ip and size of subnet (unvalidated)

>>> get_subnet(183490304, 256)
'10.239.215.0/24'
>>> get_subnet(183490304, 512)
Invalid subnet/mask cannot return 10.239.215.0/23
''

1.1.10. ipv4_octets

  • get octets in a list for provided ip/subnet

>>> ipv4_octets("10.11.12.0/24")
{'octets': ['10', '11', '12', '0'], 'mask': 24}

1.1.11. range_subset

  • check whether range1 is a subset of range2

>>> range_subset(range(0,50), range(0,100))
True
>>> range_subset(range(0,120), range(0,100))
False

1.1.12. ns-lookup

  • Use the nslookup() to get the dns name programatically.

>>> nslookup("8.8.8.8")
'dns.google'

1.1.13. IP.ping

  • Use the IP.ping_average() from nettoolkit to get the average responce time (in ms) for given ip.

>>> IP.ping_average("8.8.8.8")
289
