SonicWall Error 'Invalid IP Address'

03/26/2020 21 16882

DESCRIPTION:

This article covers a SonicWall error 'Invalid IP Address'.

RESOLUTION:

Invalid IP address with regards to its subnet:

 An IP Address is a logical numeric address that is assigned to every single computer, printer, switch, router or any other device that is part of a TCP/IP-based network. A subnet is a separate and identifiable portion of an organization's network, typically arranged on one floor, building or geographical location and a subnet mask is a 32-bit number used to differentiate the network component of an IP address by dividing the IP address into a network address and host address.

An IP address is considered valid or invalid based on the subnet mask of the network. A network contains a network ID, the usable(host) IP range and a broadcast ID. The Network ID and Broadcast ID cannot be used and this network ID and Broadcast IDs are determined by its subnet mask.

In the SonicWall, for example, under Network > Interface configuration or Network > Address object configuration, if you enter an IP which belongs to a network ID or a Broadcast ID, you will receive an 'Invalid IP Address' error message (determined by its subnet mask) and the settings are not accepted.

There are many third party websites that helps in calculating the network and its valid IP address if you provide the subnet mask.

  In the above screenshot, the IP address is invalid because the IP entered is the network address and it is not one of the usable IP range in the network. For this subnet mask, the valid scheme is

Network ID : 103.19.168.8/29(255.255.255.248)
Broadcast ID: 103.19.168.15 
HostMin : 103.19.168.9 
HostMax :  103.19.168.14
 

The IP address contains invalid characters:

 IPv4 addresses are canonically represented in dot-decimal notation, which consists of four decimal numbers, each ranging from 0 to 255, separated by dots, e.g., 192.168.1.1. Each part represents a group of 8 bits (octet) of the address. In some cases of technical writing, IPv4 addresses may be presented in various hexadecimal, octal, or binary representations. If the IP address entered contains any digit other than 0-255 or any special character instead of a dot, you will receive an 'Invalid IP Address' error message.

 In the above screenshot, the error is because there is an Invalid character for an IP address.

Resolution for SonicOS 6.5

This release includes significant user interface changes and many new features that are different from the SonicOS 6.2 and earlier firmware. The below resolution is for customers using SonicOS 6.5 firmware.

 In the above screenshot, the error is because there is an Invalid character for an IP address. In this case we have ',' instead '.'
