NAME

6       APR::IpSubnet - Perl API for accessing APRs ip_subnet structures
7

Synopsis

9         use APR::IpSubnet ();
10
11         my $ipsub = APR::IpSubnet->new($pool, "127.0.0.1");
12         $ok = $ipsub->test($sock_addr);
13

Description

15       "APR::IpSubnet" object represents a range of IP addresses (IPv4/IPv6).
16       A socket connection can be matched against this range to test whether
17       the IP it's coming from is inside or outside of this range.
18

API

20       "APR::IpSubnet" provides the following functions and/or methods:
21
22   "new"
23       Create an IP subnet represenation object
24
25         $ipsubnet = APR::IpSubnet->new($pool, $ip);
26         $ipsubnet = APR::IpSubnet->new($pool, $ip, $mask_or_numbits);
27
28       obj: "APR::IpSubnet" (class name)
29       arg1: $pool ( "APR::Pool object" )
30       arg2: $ip ( string )
31           IP address in one of the two formats: IPv4 (e.g. "127.0.0.1") or
32           IPv6 (e.g. "::1"). IPv6 addresses are accepted only if APR has the
33           IPv6 support enabled.
34
35       opt arg3: $mask_or_numbits ( string )
36           An optional IP mask (e.g. "255.0.0.0") or number of bits (e.g.
37           "15").
38
39           If none provided, the default is not to mask off.
40
41       ret: $ret ( "APR::IpSubnet object" )
42           The IP-subnet object
43
44       excpt: "APR::Error"
45       since: 2.0.00
46
47   "test"
48       Test the IP address in the socket address object against a pre-built
49       ip-subnet representation.
50
51         $ret = $ipsub->test($sockaddr);
52
53       obj: $ipsub ( "APR::IpSubnet object" )
54           The ip-subnet representation
55
56       arg1: $sockaddr ( "APR::SockAddr object" )
57           The socket address to test
58
59       ret: $ret ( boolean )
60           true if the socket address is within the subnet, false otherwise
61
62       since: 2.0.00
63
64       This method is used for testing whether or not an address is within a
65       subnet. It's used by module "mod_access" to check whether the client IP
66       fits into the IP range, supplied by "Allow"/"Deny" directives.
67
68       Example:
69
70       Allow accesses only from the localhost (IPv4):
71
72         use APR::IpSubnet ();
73         use Apache2::Connection ();
74         use Apache2::RequestRec ();
75         my $ipsub = APR::IpSubnet->new($r->pool, "127.0.0.1");
76         ok $ipsub->test($r->connection->remote_addr);
