This includes both basic validation (\f(CW\*(C`is_ipv4()\*(C'\fR and \&\f(CW\*(C`is_ipv6()\*(C'\fR) and special cases like checking whether an address belongs to a specific network or whether an address is public or private (reserved). .SH "USAGE AND SECURITY RECOMMENDATIONS" .IX Header "USAGE AND SECURITY RECOMMENDATIONS" It's important to understand that if \f(CW\*(C`is_ipv4($ip)\*(C'\fR, \f(CW\*(C`is_ipv6($ip)\*(C'\fR, or \&\f(CW\*(C`is_ip($ip)\*(C'\fR return false, then all other validation functions for that \s-1IP\s0 address family will \fIalso\fR return false. So for example, if \f(CW\*(C`is_ipv4($ip)\*(C'\fR returns false, then \f(CW\*(C`is_private_ipv4($ip)\*(C'\fR \fIand\fR \f(CW\*(C`is_public_ipv4($ip)\*(C'\fR will both also return false. .PP This means that simply calling \f(CW\*(C`is_private_ipv4($ip)\*(C'\fR by itself is not sufficient if you are dealing with untrusted input. You should always check \&\f(CW\*(C`is_ipv4($ip)\*(C'\fR as well. This applies as well when using IPv6 functions or generic functions like \f(CW\*(C`is_private_ip($ip)\*(C'\fR. .PP There are security implications to this around certain oddly formed addresses. Notably, an address like \*(L"010.0.0.1\*(R" is technically valid, but the operating system will treat \*(L"010\*(R" as an octal number. That means that \&\*(L"010.0.0.1\*(R" is equivalent to \*(L"8.0.0.1\*(R", \fInot\fR \*(L"10.0.0.1\*(R". .PP However, this module's \f(CW\*(C`is_ipv4($ip)\*(C'\fR and \f(CW\*(C`is_ip($ip)\*(C'\fR functions will return false for addresses like \*(L"010.0.0.1\*(R" which have octal components. And of course that means that it also returns false for \f(CW\*(C`is_private_ipv4($ip)\*(C'\fR \&\fIand\fR \f(CW\*(C`is_public_ipv4($ip)\*(C'\fR. .SH "FUNCTIONS" .IX Header "FUNCTIONS" All of the functions below are exported by default. .PP All functions return an untainted value if the test passes and undef if it fails. In theory, this means that you should always check for a defined status explicitly but in practice there are no valid \s-1IP\s0 addresses where the string form evaluates to false in Perl. .PP Note that none of these functions actually attempt to test whether the given \&\s-1IP\s0 address is routable from your device; they are purely semantic checks. .SS "is_ipv4($ip), is_ipv6($ip), is_ip($ip)" .IX Subsection "is_ipv4($ip), is_ipv6($ip), is_ip($ip)" These functions simply check whether the address is a valid IPv4 or IPv6 address. .ie n .SS "is_innet_ipv4($ip, $network)" .el .SS "is_innet_ipv4($ip, \f(CW$network\fP)" .IX Subsection "is_innet_ipv4($ip, $network)" This subroutine checks whether the address belongs to the given IPv4 network.
