object --+ | AddrInfo
AddrInfo(hostname, family=PR_AF_UNSPEC, flags=PR_AI_ADDRCONFIG) :Parameters: hostname : str or unicode object Either a hostname or an address string (dotted-decimal for IPv4 or a hex string for IPv6. family : int May be: - PR_AF_UNSPEC - PR_AF_INET. flags : int May be either: - PR_AI_ADDRCONFIG - PR_AI_ADDRCONFIG | PR_AI_NOCANONNAME Include PR_AI_NOCANONNAME to suppress the determination of the canonical name corresponding to hostname. An object used to encapsulate network address information for a specific host. After successful initialization the AddrInfo object will contain an ordered sequence of `NetworkAddress` objects which may be accessed via iteration or indexing. It is suggested you try connecting with the each `NetworkAddress` object in sequential order until one succeeds. Example Usage:: try: addr_info = io.AddrInfo(hostname) except Exception, e: print "ERROR: could not resolve address for %s" % hostname return for net_addr in addr_info: net_addr.port = port sock = io.Socket(net_addr.family) try: sock.connect(net_addr, timeout=io.seconds_to_interval(1)) return except Exception, e: pass print "ERROR: could not connect to %s at port %d" % (hostname, port) Note, the NSPR interface to getaddrinfo() does not provide a way to select just IPv6 addresses. The solution is filter them yourself, e.g.:: for net_addr in addr_info: if net_addr.family != io.PR_AF_INET6: continue
