Available inall subroutines.

Converts the string addr to an IP address (IPv4 or IPv6). If conversion fails, fallback will be returned.

The string must be a numeric IP address representation in the standard format, such as 192.0.2.2 or 2001:db8::1. This function does not support looking up an IP address by name.

We recommend using a fallback IP address that's meaningful for your particular Fastly service.

The inverse conversion is available as std.ip2str.

Example

if (std.str2ip("192.0.2.1", "192.0.2.2") ~ my_acl) {
  ...
}
