Free loopback ip address software for mac

Router IP Address is a small utility for discovering the dynamic IP address assigned by your Internet Service Provider (ISP) when you have a router connecting several computers to a single internet connection (cable modem, DSL, or telephone modem).

Router IP Address is simplicity itself. Just run the program and it displays the IP address that the rest of the Internet sees when you browse or communicate with various service providers. If you have a direct connection to the Internet this number should match that being used by your operating system but if you are using a router or gateway on your local network it will likely be different.

Get External IP Address is a small AppleScript that helps you determine your external IP address.
This app is for people that need an easier way to check their external IP address. It includes support for copying the address to the clipboard.

DockIP is a small application that displays your IP address in the applications Dock menu.
You can view your IP addresses easily from DockIPs dock menu or the menu bar.
It is not a true dockling, just a small application. Clicking on your IP address will then send it to the clipboard for later pasting into another application.
Enhancements:
- Preferences window with options to show IP address in Dock menu or the menu bar.

GetIPAddr 1.0 is developed to be a useful tool with which you can type in the name of a server and it will return the IP address. Possibly the most useless Cocoa app ever.

Mac No-IP will check your IP address at a given time interval checking to see if your IP has changed.

If your IP address has changed it will notify our dns servers and update the IP corresponding to your No-IP/No-IP+ hostname.

"World IP" shows you the location of IP addresses on an OpenGL 3D world model.

Just type the name of a server and see where it is hosted !

It uses the free http://netgeo.caida.org service.

IPGadget is a small calculator for verifying IPv4 address information. Given an IP address and network prefix size, IPGadget will show you:

* The subnet mask corresponding with the prefix size (eg "/24" = "255.255.255.0")
* The network address (ie, where the bits of the host portion are all zeroes)
* The broadcast address (ie, where the bits of the host portion are all ones)
* The range of valid host addresses for the subnet

IPGadget also highlights suspect addresses where:

* The IP address is either the network or broadcast address for the subnet, or is reserved (class E)
* The subnet portion of the network prefix is either all zeroes or all ones (classsic mode)
* The subnet mask is incorrect for the class of address

IPGadget is particularly useful when designing IPv4 networks. The prefix-size popup menu makes it easy to verify route aggregation or summarization masks, and the stepper quickly recalculates the address field for the next or previous subnet in sequence.

You choose whether to impose classful or classless rules. For example, sometimes its simpler to skip all-zeroes or all-ones subnets rather than waste time explaining Classless Inter-Domain Routing (CIDR) to people who should know better. Alternatively, if legacy devices in your network preclude you from using CIDR, IPGadgets online help includes an example explaining the classic rules.

IPGadget also provides a handy reference to address-class ranges, the ranges reserved for use in private internets, and the link-local range.

IP Display is a small application that displays your current external and internal IP addresses in a small floating window.
