Address pool

Today we learn about Address Pool =)

From Wikipedia, the free encyclopedia

In the context of the Internet addressing structure, an address pool is a set of Internet Protocol addresses available at any level in the IP address allocation hierarchy. At the top level, the IP address pool is managed by the Internet Assigned Numbers Authority (IANA). The total IPv4 address pool contains 4294967296 (232) addresses, while the size of the IPv6 address pool is 2128 (340282366920938463463374607431768211456) addresses.[1]

In the context of application design, an address pool may be the availability of a set of addresses (IP address, MAC address) available to an application that is shared among its users,[2] or available for allocation to users, such as in host configurations with the Dynamic Host Configuration Protocol (DHCP).

Phishing

Wikipedia :-

Phishing is a way of attempting to acquire sensitive information such as usernames, passwords and credit card details by masquerading as a trustworthy entity in an electronic communication. Communications purporting to be from popular social web sites, auction sites, online payment processors or IT administrators are commonly used to lure the unsuspecting public. Phishing is typically carried out by e-mail or instant messaging and it often directs users to enter details at a fake website whose look and feel are almost identical to the legitimate one.

Load Balancing

Wikipedia:-

Load balancing is a computer networking methodology to distribute workload across multiple computers or a computer cluster, network links, central processing units, disk drives, or other resources, to achieve optimal resource utilization, maximize throughput, minimize response time, and avoid overload. Using multiple components with load balancing, instead of a single component, may increase reliability through redundancy. The load balancing service is usually provided by dedicated software or hardware, such as a multilayer switch or a Domain Name System server. 

Kebiasaan penggunaan Load Balancer adalah untuk heavy transaction environment.

Nota Kaki:

Terfikir-fikir adakah MyEG gunakan Load Balancer sbb baru-baru ni untuk online payment manjang down. What do you think?
