Understand More About IP Blacklisting
IP blacklisting is a method that is used to filter out malicious IP addresses from getting access to your network. IP blacklists include ranges of IP addresses that you wish to block. These lists can be used in combination with intrusion prevention systems, firewalls, and other tools that are used to filter traffic. Making and applying blacklists let you filter out illegitimate or malicious traffic as per policies or via the manual addition of IP addresses. Some Challenges With IP Blacklisting Even though blacklisting can be a great way to prevent some IP addresses from gaining access to your network, it might not be a foolproof method. The reason is that attackers have come up with many different ways to[…]

Everything You Need to Know About a Subnet Mask
A subnet, or sub-network, refers to a network within a network, which is assigned to make the parent network more efficient. Administrators use subnets to facilitate effective network traffic over a shorter distance without requiring the signals to pass through multiple routers to reach the destination. A subnet mask is a 32-bit number like an IPv4 address but it masks the IP address for internal purposes and divides the IPv4 address into network address and host address. For instance, network routers employ subnet masks to route data packets to the specified destinations. In general, a subnet mask comprises of network bits that are set to 1s and host bits that are set to 0s. In any network, there are two[…]

Everything you Need to Know about Shared IPv4 Addresses
A shared IPv4 address refers to an IP address that is used for multiple websites. Such types of IP addresses are generally used by shared hosting providers or for managed server hosting that uses a cloud-based platform. Choosing a shared IP address instead of a dedicated IP address also helps to cut the costs of server hosting, although there may be some risks associated with it. Shared IPv4 addresses and shared hosting normally go together. However, having a shared IP address does not necessarily mean that it is shared hosting. Regardless, as the IP address is used by multiple websites in shared hosting, the actions of one website may affect the reputation of the other sites on the server as[…]

Why IP Address Management is Necessary
IP address management or IPAM refers to the organization of DHCP and DNS services that assign IPv4 addresses to different devices in a network. In other words, IPAM involves planning, tracking, and managing IPv4 addresses, which is usually done by DNS and DHCP services. However, with a robust IPAM software application, these network services can perform better and work in tandem to resolve common IP conflict issues. Using spreadsheets was the traditional way of managing IP addresses and tracking responsibilities in a network. This can be very taxing in the cases where the size of the IPv4 address pool is huge. Besides, maintaining data in spreadsheets can also be quite time-consuming and prone to human error. This can lead to[…]
