IP Address Validation

Introduction

This plugin validates IP addresses using regular expressions.

Usage

`` @section autotoc_md290 Mountipaddrplugin to cascading namespace/tests/ipaddr` kdb mount config.dump /tests/ipaddr dump ipaddr

Check the validity of the IP stored in `/tests/ipaddr/ipv4`

kdb meta-set /tests/ipaddr/ipv4 check/ipaddr ipv4

Try to set an incorrect IP address

kdb set /tests/ipaddr/ipv4 127.0.0.1337

STDERR: .*Validation Semantic.*

ERROR: C03200

RET: 5

Set a correct IPv4 address

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

By default the plugin allows both IPv4 and IPv6 addresses

kdb meta-set /tests/ipaddr/address check/ipaddr ""

Set correct IP addresses

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

Try to set incorrect addresses

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

RET: 5

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

RET: 5

Undo modifications to the database

kdb rm -r /tests/ipaddr kdb umount /tests/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.
