has_any_ipv4_prefix()

Returns a value indicating whether one of specified IPv4 address prefixes appears in a text.

A valid IP address prefix is either a complete IPv4 address (192.168.1.11) or its prefix ending with a dot (192., 192.168. or 192.168.1.).

IP address entrances in a text must be properly delimited with non-alphanumeric characters. For example, properly delimited IP addresses are:

"These requests came from: 192.168.1.1, 10.1.1.115 and 10.1.1.201"
"05:04:54 127.0.0.1 GET /favicon.ico 404"

Syntax

has_any_ipv4_prefix(text , ip_address_prefix [, ip_address_prefix ...] )

has_any_ipv4_prefix(text , ip_address_prefixes )

Arguments

text: The value containing the text to search in.
ip_address_prefix: String value containing the IP address prefix to look for.
ip_address_prefixes: Dynamic array containing IP address prefixes to look for.

Returns

true if the one of specified IP address prefixes is a valid IPv4 address prefix, and it was found in text. Otherwise, the function returns false.

Examples

print has_any_ipv4_prefix('05:04:54 127.0.0.1 GET /favicon.ico 404', '127.0.', '192.168.') // true

print has_any_ipv4_prefix('05:04:54 127.0.0.1 GET /favicon.ico 404', dynamic(["127.0", "192.168."])) // false, invalid IPv4 prefix

print has_any_ipv4_prefix('05:04:54 127.0.0.256 GET /favicon.ico 404', '127.0.', '192.168.') // false, invalid IPv4 address

print has_any_ipv4_prefix('05:04:54127.0.0.1 GET /favicon.ico 404', '127.0.', '192.') // false, improperly delimited IP address
