Selecting the right approach to CGNAT logging is essential for ISPs to meet regulatory compliance while balancing resource efficiency.

Hardware appliance or virtualization: Which is better for resource-intensive networking applications like CGNAT or load balancer? In this blog, we explore all possible deployment options and discuss their pros and cons.

How many subscribers can be behind one IPv4 address using CGNAT while ensuring a safe and satisfactory user experience? Let's discuss factors that impact the subscriber density for a given IPv4 address.

As CGNAT has gained wider adoption, a debate has emerged regarding the continued necessity of Application Layer Gateways (ALGs). In this blog post, we delve into arguments from both perspectives to shed light on the topic.

This blog discusses the role of Carrier Grade Network Address Translation (CGNAT) in Dual Stack networks and how it can help ISPs cope with the limited availability of IPv4 addresses.

Learn how to choose the right CGNAT solution for your organization or ISP. Explore different factors to ensure a seamless transition to CGNAT while maintaining optimal network performance and security.

Through the use of network address translation and advanced virtualization techniques, virtualized CGNAT enables internet service providers to extend the life of their IPv4 networks and manage IP address exhaustion.

Network Address Translation (NAT) and Carrier-Grade Network Address Translation (CGNAT) are two technologies that allow devices on a private network to communicate with devices on the public Internet. But what are the differfences?

Converged solutions offer CGNAT among other network functions like firewalls or routers. Is it better than a stand alone solution?

As NFV approaches its tenth anniversary, its performance, cost and scale benefits have impressed operators everywhere.

How does your IP addressing strategy change with the high cost of IPv4 addresses? The latest NFWare blog explains when you should consider moving to IPv6, expanding CGNAT or both

Here are some basic advantages of deploying virtual or software-based networking solution bare metal, relevant for almost any network function like CGNAT, Load Balancer, Firewall, URL-Filtering and others

NFWare vCGNAT plug-in became available for all service providers who use FD.io/VPP libraries and frameworks and seeking for a robust CGNAT solution.

Many companies intend to switch to a new version of the protocol. IPv6 is a fundamentally new solution with additional features that are intended to replace the ending IPv4.

We sometimes hear from others about stereotyped CGNAT complexity issues or NAT security and application problems. Let's try to go through these myths in more detail.

Some options of what carriers can do with the excess IPv4-addresses as they deployed CGNAT

The scarcity of IPv4 addresses, the most widespread IP protocol, has finally come. Now like never before operators pay a lot of attention to cost optimization.

CGNAT is not only "IPv4 to IPv4" translation, though it is the most common mode, calling NAT44 (NAT444). CGNAT also allows translating "IPv4 to IPv6" and "IPv6 to IPv4".

The NFWare team has compiled a list of required applications and created the necessary conditions to test the effects of Network Address Translation on basic applications.

Network Address Translation (NAT) is an IETF standard through which several computers or private network devices can share a single IPv4 address and there are three basic concepts in address translation (SNAT, Dynamic, PAT)

Carrier Grade NAT otherwise known as Large Scale NAT (LSN) is the next level of NAT development that allows operators to extend the use of the IPv4 address space and facilitating a smooth migration to IPv6 addressing.

The IPv4 address limitations are still here and the number of free IPv4 addresses is gradually decreasing

IPv6 (Internet Protocol version 6) is a new version of IP protocol designed to solve problems that the previous version (IPv4) encountered by using an address length of 128 bits rather than 32.

IPv4 is the fourth version of IP, it is the basis of the Internet, and establishes the rules for the computer networks functioning on the principle of packet exchange.
