CIDR Block

CIDR stands for Classless Inter-Domain Routing, which is a method of allocating IP addresses and routing Internet Protocol (IP) packets. A CIDR block is a range of IP addresses that can be assigned to devices on a network.In CIDR notation, a CIDR block is represented by an IP address followed by a forward slash (/) and a number that indicates the number of significant bits in the network address. For example, a CIDR block of would indicate that the network address is and that the first 24 bits of the IP address are used for the network portion of the address, leaving the last 8 bits for device addresses.CIDR blocks are used to create subnets within a network, which can be used to partition a larger network into smaller, more manageable segments. By assigning CIDR blocks to subnets, network administrators can control IP address allocation and routing within the network.CIDR blocks are also used to allocate IP addresses to virtual private cloud (VPC) networks in public cloud environments. In this case, the CIDR block is used to define the IP address range for the VPC and the subnets within it.

Cloud Networking

Cloud networking refers to the use of cloud computing technologies to manage, configure, and secure computer networks. This involves leveraging cloud-based infrastructure and services to deliver networking capabilities that can be easily scaled and managed.Cloud networking offers several benefits over traditional networking approaches, such as:

  1. 1.Scalability: Cloud networking allows organizations to easily scale their network infrastructure up or down as their needs change, without having to invest in additional hardware or resources.

  2. 2.Cost-effectiveness: Cloud networking can be more cost-effective than traditional networking, as it eliminates the need for organizations to invest in expensive hardware and infrastructure.

  3. 3.Flexibility: Cloud networking enables organizations to quickly and easily deploy new network resources, services, and applications as needed.

  4. 4.Security: Cloud networking offers robust security features, such as encryption and identity and access management, to protect data and resources.

  5. 5.Automation: Cloud networking can be automated to a great extent, reducing the need for manual intervention and improving network agility.

Cloud networking can take many forms, such as virtual private cloud (VPC), software-defined networking (SDN), and network function virtualization (NFV). These technologies enable organizations to build flexible, scalable, and secure networks that can adapt to changing business needs.

Cloud OnRamp

Cloud OnRamp refers to a set of networking technologies and services that enable organizations to connect and integrate their on-premises infrastructure or private cloud with public cloud environments in a secure and seamless manner.

Cloud Router

A Cloud Router is a virtual router service offered by cloud computing providers, such as Google Cloud Platform and Amazon Web Services (AWS).Cloud Router allows users to dynamically exchange routes between their Virtual Private Cloud (VPC) networks and their on-premises networks, creating a hybrid cloud environment. It also provides advanced routing features, such as Border Gateway Protocol (BGP), to optimize network performance and redundancy.With Cloud Router, users can easily manage their network infrastructure and configure routing policies from a single web-based interface. This makes it easier to connect and manage multiple VPC networks and on-premises data centers, improving network efficiency and reducing costs.Cloud Router can also be integrated with other cloud services, such as load balancing and virtual private network (VPN) gateways, to provide a complete network solution for hybrid cloud environments. This enables users to seamlessly connect and manage their cloud resources across multiple regions and availability zones.In summary, Cloud Router provides a flexible and scalable solution for managing complex network infrastructures in the cloud, enabling users to connect and optimize their network resources in a more efficient and cost-effective way.


CNAME stands for Canonical Name record. It is a type of DNS record used to associate one domain name with another domain name.In other words, a CNAME record allows a domain name to act as an alias for another domain name. When a user enters the alias domain name in their web browser, the DNS system looks up the corresponding canonical domain name associated with the CNAME record, and then resolves the IP address for that canonical domain name.


China Telecom CN2 GIA is a network architecture used by China Telecom to provide high-speed, low-latency internet connectivity to customers. CN2 is short for "China Telecom Next Generation Carrier Network," and GIA stands for "Global Internet Access."CN2 GIA is designed to provide customers with fast and reliable internet connectivity by using advanced networking technologies such as Multi-Protocol Label Switching (MPLS), Quality of Service (QoS), and Border Gateway Protocol (BGP) to optimize routing and minimize latency. The network also incorporates a number of security features, such as Distributed Denial of Service (DDoS) protection and intrusion detection and prevention systems, to help protect against cyber threats.Overall, CN2 GIA is an important part of China Telecom's strategy to provide high-quality internet connectivity to customers worldwide, particularly in the Asia-Pacific region.

Cross Connect

A cross connect is a physical cable that connects two different network devices within a data center or a carrier hotel. It is used to establish a dedicated, high-speed connection between two devices for the purpose of exchanging data with low latency and high reliability. Cross connects are commonly used to connect servers, storage devices, routers, switches, and other networking equipment, either within the same data center or across multiple data centers. Cross connects are typically leased from data center operators or carriers and can be configured in a variety of ways, including copper or fiber optic cabling and different interface types and speeds.
