How do you change your IP Address?

When you connect to the Internet, your Internet Service Provider (known as ISP) assigns an IP address. Depending on the type of service you subscribed, you may be allocated to use static or dynamic IP address. A static IP address is a permanent (non-changing) IP address assigned to you. Most users on the other hand gets an dynamically assigned IP address from their ISP. The device (a router, gateway or computer) connected to your ISP allows...

What is a VPN?

A Virtual Private Network (VPN) is a network technology which extends private network (such as LAN) over a public network such as the Internet. A VPN allows a computer (or a network) to be connected securely as if they are physically wired together. Corporations use VPN to allow remote workers to connect securely to their private network. A VPN is also used to interconnect remote offices with a head office as if they are physically connected. Besides interconnecting private networks, a VPN is also used to hide ip address or change...

My IP address is hacked. What can I do?

Many readers of our website are contacting us for help on *allegedly* hacked IP address, and remedies for getting it back. One of the user is telling us his IP address used to be 64.3.x.y in Dallas and now it's 67.72.x.y located in Utah (per ip lookup); and hence his IP address is stolen, and his computer is running very slow and acting abnormal. For a non-computer person, this may sound like a user's IP address has been hacked but in reality your IP address cannot be hacked. Chances are that you're getting your IP address dynamically from...

What is IP Spoofing?

IP Spoofing is a technique used to gain unauthorized access to machines, whereby an attacker illicitly impersonate another machine by manipulating IP packets. IP Spoofing involves modifying the packet header with a forged (spoofed) source IP address, a checksum, and the order value. Internet is a packet switched network, which causes the packets leaving one machine may be arriving at the destination machine in different order. The receiving machine resembles the message based on the order value embedded in the IP header. IP spoofing involves solving...

What is the difference between a static and dynamic IP address?

An IP address is an address assigned to a device on the Internet. It is analogous to postal address where a letter is delivered, and an IP address is computer's address where internet traffic is delivered. An IP address is assigned to you by your Internet Service Provider (ISP). When you signup with your ISP, your ISP either assigns you a static IP address or a dynamic IP address depending on the contract. If you need to setup a web server or an email service, you'll need a static IP address. If you are just browsing an Internet, you...

What is DHCP?

DHCP, Dynamic Host Configuration Protocol, is a communications protocol that dynamically assigns unique IP addresses to network devices. As a network device joins or leaves an IP-based network, DHCP automatically renews or releases an IP address. DHCP runs in a client/server mode, where server sets up a pool of available IP addresses for a network. A DHCP server also provides network gateway, subnet masks, name server addresses and amount of time ("lease") that a given IP address will be valid. A DHCP client...

What is a TCP/IP?

TCP/IP, Transmission Control Protocol/Internet Protocol, is a suite of communications protocols used to interconnect network devices on the Internet. TCP/IP implements layers of protocol stacks, and each layer provides a well-defined network services to the upper layer protocol. TCP and IP are the two protocols used by TCP/IP, as well as the (higher) application, (lower) data link and (lower) physical layer protocols. LayerProtocols 5. ApplicationDNS, FTP, HTTP, IMAP, POP3, SMTP, SSH, Telnet, SSL, ... 4. TransportTCP, UDP,...

What is Ethernet?

Ethernet is the most widely used local area network (LAN) technology, that defines wiring and signaling standards for the physical layer of TCP/IP. Ethernet was originally standardized as IEEE 802.3 with a data transmission rate of 10 Mb/s. Newer versions of Ethernet were introduced lately to offer higher data rates. Fast Ethernet and Gigabit Ethernet support data rates of 100 Mbps and 1 Gbps (1000 Mbps) respectively. An Ethernet LAN may use coaxial cable (10Base2), unshielded twisted pair wiring (10BaseT, 100BaseT and 1000BaseT), or fiber optic...

What is a MAC Address?

MAC, Media Access Control, address is a globally unique identifier assigned to network devices, and therefore it is often referred to as hardware or physical address. MAC addresses are 6-byte (48-bits) in length, and are written in MM:MM:MM:SS:SS:SS format. The first 3-bytes are ID number of the manufacturer, which is assigned by an Internet standards body. The second 3-bytes are serial number assigned by the manufacturer. MAC layer represents layer 2 of the TCP/IP (adopted from OSI Reference Model), where IP represents...

What is a Subnet Mask?

An IP address has two components, the network address and the host address. A subnet mask separates the IP address into the network and host addresses (<network><host>). Subnetting further divides the host part of an IP address into a subnet and host address (<network><subnet><host>) if additional subnetwork is needed. Use the Subnet Calculator to retrieve subnetwork information from IP address and Subnet Mask. It is called a subnet mask because it is used to identify network address of an IP address...

What is IPv6 Address?

Internet Protocol Version 6 (or IPv6) is a successor of IPv4 Address standard developed by IETF, which is designed to solve IPv4 address exhaustion problem. IPv4 uses a 32-bit numbering scheme to represent an IP address, which has an address space of 232 or 4.3 billion. IPv6, on the other hand, uses 128-bit numbering scheme (2128) which has big enough address space for many decades to come. IPv6 is intended to replace the IPv4, but the introduction of CIDR (Classless Inter-Domain Routing) allocation scheme in 1993 within the...

What is an IP Address?

Internet Protocol Address (or IP Address) is an unique address that computing devices such as personal computers, tablets, and smartphones use to identify itself and communicate with other devices in the IP network. Any device connected to the IP network must have an unique IP address within the network. An IP address is analogous to a street address or telephone number in that it is used to uniquely identify an entity. Dotted Decimals The traditional IP Addresses (known as IPv4) uses a 32-bit number to represent an IP address, and it defines...
