Socket applications often need to convert hostnames like google.com to their corresponding ip address. This is done through dns requests. The socket api in linux provides functions like gethostbyname and getaddrinfo that can be used to perform the dns requests and get the ip address. gethostbyname The first method uses the traditional gethostbyname function to Sourceware Bugzilla – Bug 12377 getaddrinfo() with AI_ADDRCONFIG won't suppress AAAA DNS queries when only IPv6 loopback and link-local addresses are present Last modified: 2016-03-17 13:59:53 UTC The getaddrinfo() function combines the functionality provided by the gethostbyname(3) and getservbyname(3) functions into a single interface, but unlike the latter functions, getaddrinfo() is reentrant and allows programs to eliminate IPv4-versus-IPv6 dependencies. The addrinfo structure used by getaddrinfo() contains the following fields If the third argument to getaddrinfo() is a null pointer, it is as if the caller had filled in an addrinfo structure initialized to 0 with ai_family set to PF_UNSPEC. Upon success, a pointer to a linked list of one or more addrinfo structures is returned through the final argument. getaddrinfo is a library function in the standard C library, not a command line tool. So trying to execute it is not quite the right path to a solution. You can call getaddrinfo from a python shell if you want: When I use "127.0.0.1" as first argument of getaddrinfo(), it prints failed to get socket name. When using "www.google.com" it prints Setting up connection from A. getaddrinfo() and getnameinfo() can be used for clients and servers alike, just as gethostbyname() and gethostbyaddr() can be. They are just host/address resolution functions, how the resolved values get used is up to the calling app to decide. B. client code using getaddrinfo() would look something like this:

Find answers to getaddrinfo and bind from the expert community at Experts Exchange The reason why it is slow is that getaddrinfo will resolve both IPV6 and IPv4 by default. If you set getaddrinfo only to resolve IPV4, the speed is the same as gethostbyname , it will communicate with DNS server twice gethostbyname and getaddrinfo are bothworking in blocked mode, C-ares library can be used to achieve asynchronous resolving. This method corresponds closely to the POSIX.1g getaddrinfo() definition. Parameters. host is a host name or an address string (dotted decimal for IPv4, or a hex string for IPv6) for which to return information. A nil is also allowed, its meaning depends on flags, see below. Hi Kai, It is possible that the connection is being blocked by a firewall or similar. Could you ask your hosts/server admin if this is the case?
