The TCP/IP (Transmission Control Protocol/Internet Protocol) is the backbone of the internet and most modern networks. It ensures that data is transmitted reliably and efficiently between devices, whether you’re sending an email, streaming a video, or browsing a website. In this blog, we’ll break down how TCP/IP works, its layers, and how data moves across … Read more

Private vs. Public Autonomous System Numbers (ASN): What’s the Difference?

Interconnection

In the world of internet networking, Autonomous System Numbers (ASNs) play a crucial role in routing data efficiently between different networks. ASNs are unique identifiers assigned to Autonomous Systems (AS)—large networks or groups of IP addresses that operate under a single organization, such as ISPs, cloud providers, or large enterprises. However, not all ASNs are … Read more

Unifi Shadow Mode

High Availability in Ubiquiti. UniFi Shadow Mode is a high-availability (HA) feature for UniFi Cloud Gateways (UDM-Pro, UDM-SE, UDM-Pro-Max, EFG) that provides instant failover by creating an active-passive pair. A secondary “Shadow” gateway mirrors the primary’s configuration and state, automatically taking over within seconds if the primary fails, using Virtual Router Redundancy Protocol (VRRP) and shared IP/state … Read more

How to Set Up an EoIP Tunnel with MikroTik Version 7

Ethernet over IP (EoIP) is a protocol developed by MikroTik that allows the creation of a Layer 2 VPN tunnel between two MikroTik devices over an IP network. This is useful for extending local networks across remote locations. In this guide, I will demonstrate how to configure an EoIP tunnel using MikroTik version 7. Prerequisites … Read more

Why Is East-West Traffic Important in ISP Networks?

The terms east-west traffic and north-south traffic are pivotal for understanding data flows. These concepts are not limited to data centers or enterprise networks; they also have significant implications in Internet Service Provider (ISP) networks. While ISPs primarily focus on external connectivity (north-south traffic), the importance of east-west traffic within their networks is growing as … Read more
