IP Address Configuration Utilities for DOS

This page collects some utilities which are used to store the dynamic IP address of a SLIP or PPP session in the DOS environment. Once stored in an environment variable, the address can be used to automatically configure various network applications.

Utilities by Frank Molzahn on Simtel.Net

• The two utilities IPRARP and IPREAD both write batch files which set the MYIP environment variable. They do this in different ways, and thus are useful in different circumstances. (Please read their documentation before use.)

  IPRARP gets the IP address directly from a class 1 packet driver interface supporting RARP (such as Merit Network's EtherPPP, or the PPPPKT shim). This method will not work with typical SLIP drivers.

  IPREAD `reads' or `grabs' the IP address directly off the screen and so should be run right after dialing in. This method, although clumsy, is more universal: it will work with SLIP and does not require a Class 1 packet driver.

  Taken together, the utilities IPRARP v0.20 and IPREAD v0.15 form the package

  • IPCONFIG v0.12 (ipcfg012.zip, 20 Kb)

There are two other programs of a similar nature that I know of:

• Mike Wright's RARPSET
• Will Baldwin's IP grabber MYIP
