Syntax
Python
from pyspark.databricks.sql import functions as dbf
dbf.try_ip_cidr(col=<col>)
Parameters
Parameter | Type | Description |
|---|---|---|
|
| A STRING or BINARY value representing a valid IPv4 or IPv6 CIDR block. |
Examples
Example 1: Canonicalize an IPv4 CIDR block.
Python
from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([('192.168.1.5/24',)], ['cidr'])
df.select(dbf.try_ip_cidr('cidr').alias('result')).collect()
Output
[Row(result='192.168.1.0/24')]
Example 2: Canonicalize an IPv6 CIDR block.
Python
from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([('2001:db8::1/64',)], ['cidr'])
df.select(dbf.try_ip_cidr('cidr').alias('result')).collect()
Output
[Row(result='2001:db8::/64')]
Example 3: Invalid input returns None.
Python
from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([('invalid.ip/24',)], ['cidr'])
df.select(dbf.try_ip_cidr('cidr').alias('result')).collect()
Output
[Row(result=None)]
Example 4: None input returns None.
Python
from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([(None,)], 'cidr: string')
df.select(dbf.try_ip_cidr('cidr').alias('result')).collect()
Output
[Row(result=None)]
