valid_str(addr, flags=0)
Returns: True if IPv6 address is valid, False otherwise.

str_to_int(addr, flags=0)
Returns: The equivalent unsigned integer for a given IPv6 address.

valid_str(addr, flags=0)

Parameters:

addr - An IPv6 address in presentation (string) format.
flags - decides which rules are applied to the interpretation of the addr value. Future use - currently has no effect.

Returns:

True if IPv6 address is valid, False otherwise.

str_to_int(addr, flags=0)

Parameters:

addr - An IPv6 address in string form.
flags - decides which rules are applied to the interpretation of the addr value. Future use - currently has no effect.

Returns:

The equivalent unsigned integer for a given IPv6 address.

int_to_str(int_val, dialect=None)

Parameters:

int_val - An unsigned integer.
dialect - (optional) a Python class defining formatting options.

Returns:

The IPv6 presentation (string) format address equivalent to the unsigned integer provided.

int_to_arpa(int_val)

Parameters:

int_val - An unsigned integer.

Returns:

The reverse DNS lookup for an IPv6 address in network byte order integer form.

int_to_packed(int_val)

Parameters:

int_val - the integer to be packed.

Returns:

a packed string that is equivalent to value represented by an unsigned integer.

packed_to_int(packed_int)

Parameters:

packed_int - a packed string containing an unsigned integer. It is assumed that string is packed in network byte order.

Returns:

An unsigned integer equivalent to value of network address represented by packed binary string.
