An IP address is an Internet Protocol address that is used to identify different devices on a network. It is like a postal address for various devices. IP addresses act as an identifier that sends information between devices on a network. Your IP address contains your device location and information required for communication.

Coming to your question ‘What is my Private IP address in Japan?’, private IP addresses are designated for use within internal networks and are not accessible from the internet. They are assigned by devices like routers, which use network address translation (NAT) to manage the traffic within the network.

Moving forward, you’ll find more details about private IP address in Japan and how do I find my private IP address in Japan on my device.

What is a Private IP Address Used For?

A Private IP address is used in home and business networks to maintain privacy and prevent visibility from external networks. Internet service providers (ISPs) may assign a single routable IPv4 address to residential customers, which is then translated into multiple IP private addresses using a network address translator/port address translator gateway. This allows multiple devices to share the address.

In corporate networks, private IP addresses enhance security by making it difficult for external hosts to connect to internal systems. Organizations use private IP addresses to restrict internet access for internal users, further strengthening security measures.

What Are the Different Private IP Address Ranges in Japan?

Private IP addressing encompasses both IPv4 and IPv6 addresses. Here are the different ranges for private IP addresses in Japan:

For IPv4:

  • Class A IP addresses: From to, this class provides a large network configuration with 8 bits for the network and 24 bits for hosts.
  • Class B IP addresses: From to, this class offers a medium-sized network configuration with 16 bits for both the network and the hosts.
  • Class C IP addresses: From to, this class is suitable for smaller networks, featuring 24 bits for the network and 8 bits for hosts.

Private IP addresses can be reused across multiple private networks without issues, giving the impression of a relatively small range. In contrast, public IP addresses must be unique and globally recognizable.

For IPv6:

  • The fc00::/7 address block: Reserved by the Internet Assigned Numbers Authority (IANA) for special local addresses.
  • The fec0::/10 address block: Intended for deprecating site-local addresses.

IPv6 addresses are written in hexadecimal, consisting of 32 hexadecimal digits grouped into eight blocks of four numbers each.

What is the Netmask?

The netmask serves to allow multiple devices to use the same IP address. It enables the identification of different devices by configuring them under different masks. As explained earlier, these masks are also responsible for dividing networks into various categories. The netmask determines the number of networks and hosts that can be created based on the type of private IP address.

Here are the netmask values for each IP class:

  • Class A IP addresses:
  • Class B IP addresses:
  • Class C IP addresses:

The common netmask often encountered is, assigned to type C networks.

To simplify, the block of 255 represents the number of networks that can exist, while the numbers of 0 indicate the number of hosts. This means there can be 255 networks and 0 hosts. However, I can have 254 hosts in practical terms since one is reserved for broadcast (usually

It’s important to note that the mentioned masks have been simplified. There are masks with different numbers, such as or, which provide specific network configurations.

What are IPv4 and IPv6 IP Addresses?

IPv4 addresses are the familiar types of addresses that I commonly encounter. On the other hand, IPv6 addresses represent a new protocol designed to replace IPv4 due to the scarcity of available IPv4 addresses. Here’s an interesting fact:

IPv4 supports approximately 4.3 billion addresses, equivalent to 2^32 addresses. In contrast, IPv6 offers many addresses, specifically 3.4 x 10^38 (2^128). To put it into perspective, this is an enormous quantity, comparable to having around 6.67126144781401e+23 IP addresses for every square meter of the Earth’s surface.

Fascinating, isn’t it? IPv6 addresses are the future, or rather, the present. Their composition differs from that of IPv4 addresses, as they incorporate alphanumeric characters. Consequently, the combinations of IPv6 addresses are virtually limitless.

What’s the Difference Between Public and Private IP Addresses in Japan?

The difference between the two types of IP addresses in Japan, public and private, is as follows:

Features Public IP Address Private IP Address
Assigned by A random IP address provided by your internet service provider (ISP) Assigned to your device directly by the network router
Purpose Allows your network to be accessible over the internet Intended for internal use within your local network
Visibility Visible and accessible through the internet Not visible or accessible from the internet
Used for Used to locate your device on the internet Allows other devices that are connected to your router to communicate with your device

FAQs: What’s My Private IP Address in Japan?

Yes, the IP address range starting with “172” is designated for private use. However, it’s important to note that only a portion of the “172” address range is reserved for private use. In contrast, the remaining addresses are public and can be routed on the global Internet.

When setting filters or configuring network settings, it is crucial to exercise caution to ensure that these private address ranges are appropriately excluded.

According to the Internet Assigned Numbers Authority (IANA), the following three IP address ranges are for private use only:

24-bit block – single class A network
20-bit block – 16 contiguous class B networks
16-bit block – 256 contiguous class C networks

Yes, 192.168 is a private IP address. In fact, it is the most common private IP address in the world – so, don’t be surprised if you see a device or two or maybe even three with this IP address in your house.

To find your private IP address on a Windows computer, first open the search bar and type “cmd” to launch the Command Prompt. Once the Command Prompt opens, type “ipconfig” and press Enter. This will display your private IP address along with other network information.

No, a private IP address cannot give away your geographic location. Private IP addresses are not tracked or restricted by websites and cannot be used to locate a user’s computer geographically. While regular IP addresses can reveal your general geolocation, they do not provide precise location information like a home address. IP addresses do not disclose your name, phone number, or other personal information.

Yes, it is normal to see traffic on private IP address numbers if you have a small home or office network. Routers and access points commonly use these numbers to assign to local computers within the network. Therefore, if you observe traffic from these IP addresses, it is likely that it represents computers within your internal network.

If you notice a private IP address number in the headers of an unsolicited email in Japan, it typically signifies the transit between servers within a corporate network or internet service provider (ISP).

It is important to note that these IP addresses do not help determine the origin of the email. To find the true origin, refer to the earliest “Received” mail header in the email.


In conclusion, the question “What is my Private IP address in Japan?” opens up a fascinating exploration into the world of internet protocols and digital communication. Moreover, I recommend vigilance in managing your private IP address to maintain network security. With the vast array of devices in modern homes and businesses, understanding the intricacies of IP management is paramount.
