IPv6: The Key to the Future of Internet Service Provider Connectivity The global internet is undergoing an inevitable transition. With the explosion of connected devices from smartphones and IoT to 5G applications, the exhaustion of IPv4 addresses is no longer a distant prediction but a real bottleneck. Since 2011, the IANA has been warning about […]
The Wi-Fi Revolution 7: How RU and MRU Are Reinventing Wireless Communication The Chaos of Data Traffic and the Need for New “Highways” The analogy between computer networks and large urban highways has never been more accurate. Dense environments with hundreds of connected devices turn frequency channels into congested avenues. Wi-Fi 7 has emerged as […]
Welcome, dear readers and network enthusiasts! If you’ve made it this far, it’s because you’ve already survived the theory of SRv6 (Segment Routing IPv6) in our first two articles. If you haven’t already, I recommend taking a look at them so you don’t feel as lost as a packet without a router.After all, nobody wants […]
In this article we will talk about the process of reconfiguring Nokia G-1425-GA routers after they have been reset. In order for them to be completely reconfigured to the state they were in before the reset, an ACS TR-069 server must be up and running, persisting its previous settings. If you don’t know what an […]
Today we’re going to explore the famous DHCP Option 43, used mainly to autoconfigure devices such as Access Points, Switches, IP Phones, CPEs, IoT devices and others through TR-069. We will also show a configuration example using the DHCP Server of a Mikrotik router, delivering parameters via DHCP Option43 and allowing autoconfiguration of services in […]
Introduction When we talk about servers today, we automatically associate them with virtualization. Gone are the days when we used bare-metal servers to run just one application. With the ease of virtualization and better use of server resources, it has become almost mandatory to use your server with some virtualization software. Currently, two big names […]
Overview: BGP FlowSpec (Border Gateway Protocol Flow Specification) is an extension of the BGP protocol used to define traffic filtering rules on routers or, more simply, to generate firewall rules on routers from a BGP announcement. Unlike conventional BGP, which routes based on IPv4/IPv6 and prefix information, BGP FlowSpec allows network administrators to specify more […]
In an increasingly interconnected world, network security is a primary concern for internet provider companies and their customers. An essential tool for protecting your IT infrastructure against cyber threats is the firewall. In this article, we’ll explore why using firewalls is critical and how to implement them effectively on your network.
The new release focuses on simplifying Zabbix configuration, allowing Zabbix to instantly propagate configuration changes across large, distributed environments, as well as streamlining software update workflows. Organizations using LDAP or SAML will benefit from the new Just-in-time (JIT) user provisioning capabilities, allowing IT administrators to propagate Zabbix users using centralized user authentication mechanisms. This update […]
In this post we will discuss a very common (and little documented) scenario, which is to use a GRE tunnel secured with IPSec between a Cisco IOS ASR1002 router and a Huawei NE40 router. The topology for this example is described below. It has been kept simple so that we can discuss the details of […]
