"The Ultimate Guide to OHP Pacific Source Address: How to Find It Easily"

By Sarah WilsonDecember 13, 2025

The term "OHP" in the context of networking refers to Over-the-Horizon Radar, a system used to detect and track objects, such as aircraft or ships, beyond the visual range or line-of-sight. However, when combined with "Pacific" and "Source Address," it leads us down a different path, pointing towards Internet Protocol (IP) addressing. Let's delve into the world of IP addressing and explore the Pacific Source Address, an essential concept in understanding and managing IP addresses.

IP addresses are numerical labels assigned to devices connected to a computer network that use the Internet Protocol for communication. They serve as a unique identifier for each device, allowing them to communicate with each other over the internet. The Pacific Source Address is a region-specific aspect of IP addressing, tied to the geographic location of the devices.

The IPv4 Addressing Scheme

Before diving into the Pacific Source Address, it's crucial to understand the basics of the IPv4 addressing scheme. IPv4 uses 32-bit numbers, divided into four 8-bit fields, separated by periods (e.g., 192.0.2.1). Each field can range from 0 to 255, defining a total of 4.3 billion unique addresses.

IPv4 addresses are further classified into five main categories: A, B, C, D, and E. These classes define the network size and the range of addresses assigned to hosts within that network.

IP Address Classes

Class A addresses start with a value from 1 to 126. They have the largest network size, supporting over 16 million hosts. Class B addresses use values from 128 to 191, offering around 65,000 hosts per network. Class C addresses range from 192 to 223 and can host up to 254 hosts. Class D addresses are reserved for multicasting, and Class E addresses are for future use.

Understanding IP address classes is essential when managing network configuration, subnetting, and routing. Proper planning and allocation ensure efficient use of available addresses, reducing the risk of address exhaustion.

Public vs. Private IP Addresses

Public IP addresses are globally unique and assigned by Internet Service Providers (ISPs). They identify a device on the internet and allow communication between devices across different networks. Private IP addresses, on the other hand, are used to uniquely identify devices within a private network but are not directly routed over the internet.

Private IP addresses fall within three ranges: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. These ranges were reserved by the RFC 1918 for use as private addresses and help conserve publicly routable IP addresses.

The Pacific Source Address

Now that we've covered the basics of IP addressing, we can discuss the Pacific Source Address in more detail. The Pacific region has been allocated several IP address ranges by the Regional Internet Registry (RIR) responsible for managing IP address distribution in the Asia-Pacific region.

Here are some key Pacific Source Address ranges:

13.105.64.0/18 - assigned to Australia's MetroNet
139.184.0.0/15 - allocated to New Zealand's Vodafone
202.154.16.0/20 - assigned to Fiji's FINTEL

Understanding the Pacific Source Address and its corresponding organizations can help network administrators configure their systems correctly, optimize routing, and ensure smooth connectivity within the region.

Pacific Source Addresses and Network Provisioning

Knowing the Pacific Source Address facilitates better network provisioning and management. When establishing new network links, obtaining the appropriate source address range ensures compatibility with the target network and prevents address conflicts.

Moreover, familiarizing oneself with the Pacific Source Addresses helps in trouble-shooting connectivity issues. Understanding the IP address ranges used by different network providers in the region can simplify the process of identifying and resolving routing problems or network failures.

In the dynamic and interconnected world of networking, understanding IP addressing and the Pacific Source Address is essential for effective network management and reliable communication. As networks continue to grow and evolve, staying informed about regional IP address allocations ensures the smooth operation and interoperability of systems within the Pacific region and beyond. With this knowledge in hand, network administrators can face the challenges of tomorrow's digital landscape with confidence and agility.
