This article is about the Korea-US coalition network. For information about the US military radio IP network, see RIPRNet. For information about the radio station, see Rhode Island Public Radio
The RIPRNet (Releasable Internet Protocol Router Network) is a TCP/IP based computer network for joint ROK-US access, analogous to the SIPRNet.
Whereas SIPRNet is the de facto SECRET-level TCP/IP network for general use, RIPR is for information classified as Releasable to the Republic of Korea and US Secret. In other words, RIPR is a secure coalition network for joint ROK-US usage.
Like SIPR and NIPR, it is commonly pronounced "ripper".
