In OVSDB 3 node cluster northbound remote ip address validation missing in configuration data store

Observation : 1 (Passing valid remote ip)

I used valid remote ip as "10.106.138.128"

"option": "remote_ip",
"value" : "10.106.138.128"

Bridge creation successful and the data reflected in both configuration and operational data store.

Observation : 2 (Passing invalid remote ip)

I changed the remote ip value as "1234.5678.1155.5555". The data will be reflected in configuration data store.
In operational data store there is no change.

"option": "remote_ip",
"value" : "1234.5678.1155.5555"

Bridge creation successful in configuration data store and updated with invalid remote ip as below.

<options xmlns="urn:opendaylight:params:xml:ns:yang:ovsdb">
<option>remote_ip</option>
<value>1234.5678.1155.5555</value>
</options>

In operational data store there is no update.

Observation : 3 (Passing special characters)

I changed the remote ip value as "!@#$%^&*()". The data reflected in config data store as below.

<options xmlns="urn:opendaylight:params:xml:ns:yang:ovsdb">
<option>remote_ip</option>
<value>!@#$%^&*()</value>
</options>

In operational data store there is no update.

Many times I have tried, but I got the above behavior.

For your information I have attached restconf url, config and operational data store output.
