[[esql-to_ip]]
|
|
=== `TO_IP`
|
|
Converts an input string to an IP value.
|
|
|
|
The input can be a single- or multi-valued field or an expression.
|
|
|
|
Example:
|
|
|
|
[source.merge.styled,esql]
|
|
----
|
|
include::{esql-specs}/ip.csv-spec[tag=to_ip]
|
|
----
|
|
[%header.monospaced.styled,format=dsv,separator=|]
|
|
|===
|
|
include::{esql-specs}/ip.csv-spec[tag=to_ip-result]
|
|
|===
|
|
|
|
Note that in the example above the last conversion of the string isn't
|
|
possible. When this happens, the result is a *null* value. In this case a
|
|
_Warning_ header is added to the response. The header will provide information
|
|
on the source of the failure:
|
|
|
|
`"Line 1:68: evaluation of [TO_IP(str2)] failed, treating result as null. Only first 20 failures recorded."`
|
|
|
|
A following header will contain the failure reason and the offending value:
|
|
|
|
`"java.lang.IllegalArgumentException: 'foo' is not an IP string literal."`
