IP functions

This section explains how to use IP functions in APL.

The table summarizes the IP functions available in APL.

Function	Description
format_ipv4	Parses input with a netmask and returns string representing IPv4 address.
geo_info_from_ip_address	Extracts geographical, geolocation, and network information from IP addresses.
has_any_ipv4	Returns a Boolean value indicating whether the specified column contains any of the given IPv4 addresses.
has_any_ipv4_prefix	Returns a Boolean value indicating whether the IPv4 address matches any of the specified prefixes.
has_ipv4	Returns a Boolean value indicating whether the given IPv4 address is valid and found in the source text.
has_ipv4_prefix	Returns a Boolean value indicating whether the given IPv4 address starts with a specified prefix.
ipv4_compare	Compares two IPv4 addresses.
ipv4_is_in_range	Checks if IPv4 string address is in IPv4-prefix notation range.
ipv4_is_in_any_range	Returns a Boolean value indicating whether the given IPv4 address is in any specified range.
ipv4_is_match	Returns a Boolean value indicating whether the given IPv4 matches the specified pattern.
ipv4_is_private	Checks if IPv4 string address belongs to a set of private network IPs.
ipv4_netmask_suffix	Returns the value of the IPv4 netmask suffix from IPv4 string address.
parse_ipv4	Converts input to long (signed 64-bit) number representation.
parse_ipv4_mask	Converts input string and IP-prefix mask to long (signed 64-bit) number representation.

IP-prefix notation

You can define IP addresses with IP-prefix notation using a slash (/) character. The IP address to the left of the slash is the base IP address. The number (1 to 32) to the right of the slash is the number of contiguous bits in the netmask. For example, 192.168.2.0/24 has an associated net/subnetmask containing 24 contiguous bits or 255.255.255.0 in dotted decimal format.
