inet_ntop()

def Milter.pyip6.inet_ntop

(

s

)

Convert ip6 address to standard hex notation.

Examples:

>>> inet_ntop(struct.pack("!HHHHHHHH",0,0,0,0,0,0xFFFF,0x0102,0x0304))
'::FFFF:1.2.3.4'

>>> inet_ntop(struct.pack("!HHHHHHHH",0x1234,0x5678,0,0,0,0,0x0102,0x0304))
'1234:5678::102:304'

>>> inet_ntop(struct.pack("!HHHHHHHH",0,0,0,0x1234,0x5678,0,0x0102,0x0304))
'::1234:5678:0:102:304'

>>> inet_ntop(struct.pack("!HHHHHHHH",0x1234,0x5678,0,0x0102,0x0304,0,0,0))
'1234:5678:0:102:304::'

>>> inet_ntop(struct.pack("!HHHHHHHH",0,0,0,0,0,0,0,0))
'::'

inet_pton()

def Milter.pyip6.inet_pton

(

p

)

Convert ip6 standard hex notation to ip6 address.

Examples:

>>> struct.unpack('!HHHHHHHH',inet_pton('::'))
(0, 0, 0, 0, 0, 0, 0, 0)

>>> struct.unpack('!HHHHHHHH',inet_pton('::1234'))
(0, 0, 0, 0, 0, 0, 0, 4660)

>>> struct.unpack('!HHHHHHHH',inet_pton('1234::'))
(4660, 0, 0, 0, 0, 0, 0, 0)

>>> struct.unpack('!HHHHHHHH',inet_pton('1234::5678'))
(4660, 0, 0, 0, 0, 0, 0, 22136)

>>> struct.unpack('!HHHHHHHH',inet_pton('::FFFF:1.2.3.4'))
(0, 0, 0, 0, 0, 65535, 258, 772)

>>> struct.unpack('!HHHHHHHH',inet_pton('1.2.3.4'))
(0, 0, 0, 0, 0, 65535, 258, 772)

>>> try: inet_pton('::1.2.3.4.5')
... except ValueError as x: print(x)
::1.2.3.4.5
