IP 101: The Basics of IP Addresses

Steve Krause. Hi I wanna know how to make my IP address untraceable and private. Please advise your soonest thank you! If it did not work for you you did something wrong. The instructions were laid out very simply. Pal Trend. Sherise Loper. The IP address you're using at any given time is your device's "digital address" that allows a connection to the systematically laid-out, interconnected grid that governs global connectivity. When anyone pops a letter in a mail box, you don't think about its route, or how many trucks the postal office uses, or how many packages the letter carrier delivers a day.

You just want it to go the right address.

The common type of IP address is known as IPv4, for "version 4". Here's an example of what an IP address might look like:. An IPv4 address consists of four numbers, each of which contains one to three digits, with a single dot. Each of the four numbers can range from 0 to Thanks to our IP addresses, we're pretty much guaranteed that our emails will come and go as expected, and that all our Google searches and website visits will work to perfection.

IP addresses connect automatically in the background, so we can focus on what's important. This versatile group of segmented numbers create the addresses that lets you and everyone around the globe to send and retrieve data over our Internet connections. Without this numeric protocol, sending and receiving data over the World Wide Web would be impossible. Suddenly, major companies even Microsoft! The past decade has seen explosive growth in mobile devices including mobile phones, notebook computers, and wireless handheld devices.

The format for IPv4 wasn't designed to handle the sheer number of IP addresses. Whereas IPv4 supports a maximum of approximately 4. Since the modems are usually powered on for extended periods of time, the address leases are usually set to long periods and simply renewed.

If a modem is turned off and powered up again before the next expiration of the address lease, it often receives the same IP address. Address block These addresses are not routable and, like private addresses, cannot be the source or destination of packets traversing the Internet. When the link-local IPv4 address block was reserved, no standards existed for mechanisms of address autoconfiguration. An IP address conflict occurs when two devices on the same local physical or wireless network claim to have the same IP address. A second assignment of an address generally stops the IP functionality of one or both of the devices.

Many modern operating systems notify the administrator of IP address conflicts. IP addresses are classified into several classes of operational characteristics: unicast, multicast, anycast and broadcast addressing. It normally refers to a single sender or a single receiver, and can be used for both sending and receiving.

Usually, a unicast address is associated with a single device or host, but a device or host may have more than one unicast address. Sending the same data to multiple unicast addresses requires the sender to send all the data many times over, once for each recipient. Broadcasting is an addressing technique available in IPv4 to address data to all possible destinations on a network in one transmission operation as an all-hosts broadcast. All receivers capture the network packet.

The address In addition, a more limited directed broadcast uses the all-ones host address with the network prefix. For example, the destination address used for directed broadcast to devices on the network IPv6 does not implement broadcast addressing, and replaces it with multicast to the specially defined all-nodes multicast address. A multicast address is associated with a group of interested receivers. In IPv4, addresses In either case, the sender sends a single datagram from its unicast address to the multicast group address and the intermediary routers take care of making copies and sending them to all interested receivers those that have joined the corresponding multicast group.

Like broadcast and multicast, anycast is a one-to-many routing topology. However, the data stream is not transmitted to all receivers, just the one which the router decides is closest in the network. Anycast addressing is an built-in feature of IPv6. Anycast methods are useful for global load balancing and are commonly used in distributed DNS systems. A host may use geolocation software to deduce the geolocation of its communicating peer. Public IP addresses may be used for communication between hosts on the global Internet.

For security and privacy considerations, network administrators often desire to restrict public Internet traffic within their private networks. The source and destination IP addresses contained in the headers of each IP packet are a convenient means to discriminate traffic by IP address blocking or by selectively tailoring responses to external requests to internal servers. This is achieved with firewall software running on the network's gateway router.

A database of IP addresses of permissible traffic may be maintained in blacklists or whitelists. Multiple client devices can appear to share an IP address, either because they are part of a shared hosting web server environment or because an IPv4 network address translator NAT or proxy server acts as an intermediary agent on behalf of the client, in which case the real originating IP address might be masked from the server receiving a request.

A common practice is to have a NAT mask many devices in a private network. Only the "outside" interface s of the NAT needs to have an Internet-routable address. In residential networks, NAT functions are usually implemented in a residential gateway. In this scenario, the computers connected to the router have private IP addresses and the router has a public address on its external interface to communicate on the Internet. The internal computers appear to share one public IP address. Computer operating systems provide various diagnostic tools to examine network interfaces and address configuration.

Microsoft Windows provides the command-line interface tools ipconfig and netsh and users of Unix-like systems may use ifconfig , netstat , route , lanstat, fstat , and iproute2 utilities to accomplish the task.
