Internet Protocol Suite

What is Internet Protocol Suite

The Internet protocol suite, according to WikipediA, is the conceptual model and set of communications protocols used in the Internet and similar computer networks. It is commonly known as TCP/IP because the foundational protocols in the suite are the Transmission Control Protocol (TCP) and the Internet Protocol (IP). It is occasionally known as the Department of Defense (DoD) model because the development of the networking method was funded by the United States Department of Defense through DARPA.

The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received. This functionality is organized into four abstraction layers, which classify all related protocols according to the scope of networking involved. From lowest to highest, the layers are the link layer, containing communication methods for data that remains within a single network segment (link); the internet layer, providing internetworking between independent networks; the transport layer, handling host-to-host communication; and the application layer, providing process-to-process data exchange for applications.

The technical standards underlying the Internet protocol suite and its constituent protocols are maintained by the Internet Engineering Task Force (IETF). The Internet protocol suite predates the OSI model, a more comprehensive reference framework for general networking systems.

Internet Protocol suite (IP suite), according towhatis.techtarget.com, is the standard network model and communication protocol stack used on the Internet and on most other computer networks. While other networking models exist, the IP suite is overwhelmingly the global standard for computer-to-computer communication.

The IP suite follows a client/server model, in which multiple client programs share the services of a common server program. Protocols in the suite define end-to-end data handling methods for everything from packetizing, addressing and routing to receiving. Broken down into layers the IPS includes the link layer, the internet layer, the transport layer, application layer and the physical layer. Each layer contains a number of protocols for communications. The suite is sometimes just called TCP/IP, because those are the predominant protocols in the model and were the first ones used. However, the IP suite involves many other protocols.

VoIP - Voice Over Internet Protocol

What is VoIP - Voice Over Internet Protocol?

According to voip-info.org, VoIP is an acronym for Voice Over Internet Protocol, or in more common terms phone service over the Internet. If you have a reasonable quality Internet connection you can get phone service delivered through your Internet connection instead of from your local phone company.

Some people use VOIP in addition to their traditional phone service, since VOIP service providers usually offer lower rates than traditional phone companies, but sometimes doesn’t offer 911 service, phone directory listings, 411 service, or other common phone services. While many VoIP providers offer these services, consistent industry-wide means of offering these are still developing.

Voice over Internet Protocol (VoIP), also called IP telephony, according to WikipediA, is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).

Early providers of voice-over-IP services offered business models and technical solutions that mirrored the architecture of the legacy telephone network. Second-generation providers, such as Skype, built closed networks for private user bases, offering the benefit of free calls and convenience while potentially charging for access to other communication networks, such as the PSTN. This limited the freedom of users to mix-and-match third-party hardware and software. Third-generation providers, such as Google Talk, adopted the concept of federated VoIP - which is a departure from the architecture of the legacy networks. These solutions typically allow dynamic interconnection between users on any two domains on the Internet when a user wishes to place a call.

In addition to VoIP phones, VoIP is also available on many personal computers and other Internet access devices. Calls and SMS text messages may be sent over mobile data or Wi-Fi. VoIP allows modern communications technologies (including telephones, smartphones, voice and video conferencing, email, and presence detection) to be consolidated using a single unified communications system.

ManageEngine OpUtils IP Address Management

OpUtils IP Address Management Software

OpUtils IP Address Management (IPAM) provides a centralized management of the IP address space, including IPv4 and IPv6 Address Management. IP manager software helps network engineers to identify whether an IP Address is currently available or not, in an enterprise network. The IP Address Manager tool periodically scans a subnet and provides the availability status of IP addresses in that subnet. One can check whether a particular IP is reserved or available using IP manager tool. The tool accepts multiple subnet inputs, which helps in scanning the entire network to get the status of the IP addresses.

Why OpUtils for IP Address monitor?

OpUtils IPAM helps you keeping track of all your IP Addresses. IP manager software allows you to define a hierarchy to add all your subnets based on their usage/location and then scan them to get the current status of each of the IP Addresses.

The IP manager tool main features include:

  • Active Directory Integration to check whether the IP pertains to a computer object;
  • Role Based Administration to exercise more control by creating users with Administrator or Technician Roles;
  • Hierarchial Tree View to create an hierarchical representation of their network;
  • IP History and audit to track and audit the changes made using IP Address Manager;
  • End-to-End IP details to scan the subnets to get the details of the IP Addresses;
  • Discovering and adding subnets to discover and add subnets for monitoring and managing;
  • IP Address Management Reports to provide the IP Availability Report of the network;
  • DHCP server monitoring to support Microsoft DHCP Servers;
  • Flexible Scanning to scan manually or can be scheduled to run at specified intervals;
  • Powerful Search to use the global search option to get the details of an IP Address;
  • Alert Notification to notify the administrators about the change in state of an IP Address by email;
  • Network tools for getting the current availability, DNS name, etc., of any IP Address.

IP address management

What is IPAM (IP Address Management)?

IP address management (IPAM), according to WikipediA, is a methodology implemented in computer software for planning and managing the assignment and use of IP addresses and closely related resources of a computer network. It does not typically provide Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) services, but manages information for these components.

Additional functionality, such as controlling reservations in DHCP and other data aggregation and reporting capabilities, is also common. Data tracked by an IPAM system may include information such as IP addresses in use, and the associated devices and users. Centralized collection of this information may support troubleshooting and abuse investigations.

IPAM tools are increasingly important as new IPv6 networks are deployed with large address pools of 128-bit hexadecimal numbers and new subnetting techniques.

IPAM (IP Address Management), according to Infoblox, is the administration of DNS and DHCP, which are the network services that assign and resolve IP addresses to machines in a TCP/IP network. Simply put, IPAM is a means of planning, tracking, and managing the Internet Protocol address space used in a network. Most commonly, tools such as DNS and DHCP are used in tandem to perform this task, though true IPAM will glue these services together so that each is aware of changes in the other (for instance DNS knowing of the IP address taken by a client via DHCP, and updating itself accordingly).
