std.str2ip()
Converts the string representation of an IP address (IPv4 or IPv6) into an IP type. If conversion fails, the fallback will be returned. The string must be a numeric IP address representation in the standard format such as 192.0.2.2 and 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.
Format
