IP Address Validation

Introduction

This plugin validates IP addresses using regular expressions.

Usage

`` <h1>Mountipaddrplugin to cascading namespace/examples/ipaddr` kdb mount config.dump /examples/ipaddr dump ipaddr

Check the validity of the IP stored in /examples/ipaddr/ipv4

kdb setmeta /examples/ipaddr/ipv4 check/ipaddr ipv4

Try to set an incorrect IP address

kdb set /examples/ipaddr/ipv4 127.0.0.1337

STDERR: .*value of key is not a valid IP Address.*

ERROR: 51

RET: 5

Set a correct IPv4 address

kdb set /examples/ipaddr/ipv4 127.0.0.1 kdb get /examples/ipaddr/ipv4 #> 127.0.0.1

By default the plugin allows both IPv4 and IPv6 addresses

kdb setmeta /examples/ipaddr/address check/ipaddr ""

Set correct IP addresses

kdb set /examples/ipaddr/address 1.2.3.4 kdb set /examples/ipaddr/address ::1

Try to set incorrect addresses

kdb set /examples/ipaddr/address bad::ip

RET: 5

kdb set /examples/ipaddr/address 1.2.-3.4

RET: 5

Undo modifications to the database

kdb rm -r /examples/ipaddr kdb umount /examples/ipaddr ```

Limitations

The plugin only checks IP addresses for validity. It is not able to resolve hostnames. If you are looking for a plugin that supports hostnames, check out the network plugin.
