inet_ntoa perl的ipv6

Question

我是新來的perl，我試圖將網絡格式的ipv6地址轉換爲ascii字符串格式。我可以使用「Socket」模塊中的「inet_ntoa」函數爲ipv4地址做到這一點。如何在不安裝任何新模塊的情況下爲ipv6地址執行此操作？

Answer 1

使用inet_ntop所推薦的perldoc Socket：

$字符串= INET_NTOA $ IP_ADDRESS

Takes a packed binary address structure such as returned by 
    unpack_sockaddr_in() (or a v-string representing the four octets of the 
    IPv4 address in network order) and translates it into a string of the form 
    "d.d.d.d" where the "d"s are numbers less than 256 (the normal 
    human-readable four dotted number notation for Internet addresses). 

    This IPv4-only function is provided largely for legacy reasons. 
    Newly-written code should use getnameinfo() or inet_ntop() instead for 
    IPv6 support. 

$字符串= inet_ntop $家庭，$地址

Takes an address family and a packed binary address structure and 
    translates it into a human-readable textual representation of the address; 
    typically in "d.d.d.d" form for "AF_INET" or "hhhh:hhhh::hhhh" form for 
    "AF_INET6". 
    See also getnameinfo() for a more powerful and flexible function to turn 
    socket addresses into human-readable textual representations.
