Network objects В¶ДЄll attributes implemented by address objects are implemented by network Host mask equivalent to /24 in IPv4 is 0.0.0.255.

(for example in Cisco access control lists) to denote a network mask. Host mask is the logical inverse of a net mask, and is sometimes used Thus the prefix /24 is equivalent to the net maskДў55.255.255.0 in IPv4, or ffff:ff00:: in IPv6. A net mask is an IP address with some number of A prefix / is a notation that denotes how many high-order bits are set in There are several equivalent ways to specify IP network masks. The network address 192.168.1.0 consists of IP addresses in the inclusive For example, a network definition with the mask 255.255.255.0 and IP addresses that equal the network address when masked (binary AND) with the A network definitionД¬onsists of a mask and a network address, and as such defines a range of The IPv4Network and IPv6Network objects provide a mechanismДЇor defining and inspecting IP network definitions.

Write display code that can handle both IPv4 and IPv6 addresses. Exposing these attributes makes it easier to Set to zero, these two attributes are always the same as str(addr)ДЇor IPv4 addresses. Leading zeroesДЄre never included in the representation.ДЄs IPv4 does not define a shorthand notation for addresses with octets The string representation in dotted decimal notation. The prefix defines the number of leading bits in an address thatДЄre compared to determine whether or not an address is part of a The total number of bits in the address representation for this The appropriate version number: 4 for IPv4, 6 for IPv6.

The IPv4Address and IPv6Address objects share a lot of commonДЄttributes. Obtained by calling the appropriate version specific class constructorsДirectly. Information on the precise error, as the functions donвЂ™t know whether the IPv4 and IPv6 formats means that error messages provide minimal One downside of these convenience functions is that the need to handle both ValueError is raised if address does not represent a valid IPv4 or Integers less than 2**32 will be considered to be IPv4 by default.
