throw (InvalidNetmaskLength) | IPvXNet |
Constructor from a given base address and a prefix length.
Parameters:
| a | base address for the subnet. |
| prefix_len | length of subnet mask. |
| bool is_ipv4 ()
| is_ipv4 |
[const]
Test if this subnet is IPv4 subnet.
Returns: true if the subnet is IPv4.
| bool is_ipv6 ()
| is_ipv6 |
[const]
Test if this subnet is IPv6 subnet.
Returns: true if the subnet is IPv6.
| IPv4Net get_ipv4net ()
throw (InvalidCast) | get_ipv4net |
[const]
Get IPv4Net subnet.
Returns: IPv4Net subnet contained with IPvXNet structure.
| IPv6Net get_ipv6net ()
throw (InvalidCast) | get_ipv6net |
[const]
Get IPv6Net subnet.
Returns: IPv6Net subnet contained with IPvXNet structure.
| void get (IPv4Net& to_ipv4net)
throw (InvalidCast) | get |
[const]
Assign address value to an IPv4Net subnet.
Parameters:
| to_ipv4net | IPv4Net subnet to be assigned IPv4Net value contained within this subnet. |
| void get (IPv6Net& to_ipv6net)
throw (InvalidCast) | get |
[const]
Assign address value to an IPv6Net subnet.
Parameters:
| to_ipv6net | IPv6Net subnet to be assigned IPv6Net value contained within this subnet. |
| int af ()
| af |
[const]
Get the address family.
Returns: the address family of this subnet (AF_INET or AF_INET6).
| bool is_unicast ()
| is_unicast |
[const]
Test if this subnet is a unicast prefix.
In case of IPv4 all prefixes that fall within the Class A, Class B or Class C address space are unicast. In case of IPv6 all prefixes that don't contain the multicast address space are unicast. Note that the default route (0.0.0.0/0 for IPv4 or ::/0 for IPv6) is also considered an unicast prefix.
Returns: true if this subnet is a unicast prefix.
| IPvXNet ip_multicast_base_prefix (int family)
throw (InvalidFamily) | ip_multicast_base_prefix |
[static]
Return the subnet containing all multicast addresses.
Note that this is a static function and can be used without a particular object. Example: IPvXNet my_prefix = IPvXNet::ip_multicast_base_prefix(my_family);
Parameters:
| family | the address family. |
Returns: the multicast base prefix address for address family of family.
| IPvXNet ip_class_a_base_prefix (int family)
throw (InvalidFamily) | ip_class_a_base_prefix |
[static]
Return the subnet containing all IPv4 Class A addresses (0.0.0.0/1).
This method applies only for IPv4. Note that this is a static function and can be used without a particular object. Example: IPvXNet my_prefix = IPvXNet::ip_class_a_base_prefix(my_family);
