TOP 20 SPEEDTEST SITE TOP 20 SPEEDTEST SITE, here are the steps to perform an internet speed test: Choose a speed test site that you trust (such as one of the sites mentioned in my previous answer). Connect your device to your internet network (wired or wireless). Close any unnecessary applications or downloads that may interfere with the speed test. …

What is IPv4 Subnetting IPv4 Subnetting, IP subnetting is a process of dividing a single IP network into multiple smaller subnetworks, or subnets. Subnetting allows network administrators to segment a large IP network into smaller, more manageable subnetworks, which can help improve network performance, security, and scalability. Subnetting involves dividing the host portion of an IP address into multiple subnets …

Virtual Routing and Forwarding (VRF) Virtual Routing and Forwarding (VRF) is a technology used in computer networking that enables multiple instances of a routing table to coexist on a single router. Each of these instances, known as a Virtual Routing and Forwarding instance (VRF instance), is isolated from the others and functions as if it were a separate router with …

NETWORK LOOP A network loop is a situation in which data packets in a computer network continuously circulate through the network, creating a loop. This can lead to a degradation of network performance and even cause the network to become unusable. Network loops can occur when there are multiple paths between network devices, and these paths are not properly configured …

EIGRP (Enhanced Interior Gateway Routing Protocol) is a Cisco proprietary routing protocol used in computer networks to exchange routing information between routers. It is an Interior Gateway Protocol (IGP) and is commonly used in large enterprise networks to provide a scalable and reliable routing solution. EIGRP uses a hybrid routing protocol that combines elements of both distance vector and link-state …

OSPF (Open Shortest Path First) OSPF (Open Shortest Path First) is a routing protocol used in computer networks to exchange routing information between routers. It is an Interior Gateway Protocol (IGP) and is commonly used in large enterprise networks to provide a scalable and reliable routing solution. OSPF uses a link-state routing (LSR) algorithm to build a topology database of …

Border Gateway Protocol (BGP) Border Gateway Protocol (BGP) is a routing protocol that is used to exchange routing information between different autonomous systems (ASes) on the internet. It is the standard protocol used by internet service providers (ISPs) to communicate with each other to determine the best path for data to flow between networks. BGP operates by exchanging routing information …
