    发现好多人问我要IP, 现在把我常用script 贡献给大家.

    发法很多, 一个是 nslookup host.name

    另一简单方法是用如下script :

    #!/usr/local/bin/perl
    # gethostbyname.pl - Answer IP queries

    $prog = substr ($0, rindex ($0, /) + 1);

    if ($#ARGV != 0) {
    die "usage: $prog ( hostname ) "; }
    &name_to_address ($ARGV[0]);
    exit (0);

    sub name_to_address { local ($name) = shift (@_); local (@octets);
    local ($nam, $aliases, $addrtype, $length, $address) =
    gethostbyname ($name);

    if (! length ($address)) { die "$prog: no address found for $name "; }
    @octets = unpack ("CCCC", $address);
    print (join (., @octets[0..3]), " "); }

    --
    blast email : [email protected]bsp;for $name "; }
