IRRToolSet maintenance moved from RIPE NCC to ISC
by Shane Kerr 17 Dec '04

17 Dec '04

Colleagues, We are happy to announce that the maintenance for the IRRToolSet has moved from the RIPE NCC to the Internet Systems Consortium (ISC). Starting now, ISC will support software development and maintenance of this suite. The new web page for this is: http://www.isc.org/sw/IRRToolSet/ The mailing list has been moved. The new address is <irrtoolset(a)isc.org>. E-mail will be forwarded from the existing mailing list (*). The RIPE NCC believes that ISC's software development model matches the IRRToolSet requirements, and that ISC will be a better home for the software. Operators and developers will have a set-up that is more typical to collaborative open source software, from a company that is experienced and focused on it. The RIPE NCC is grateful to ISC for agreeing to maintain this useful set of tools. We will continue to provide support for RIPE-specific portions and work with ISC in refining the software. -- Shane Kerr Software Manager RIPE NCC (*) When the mailing list forwarding began, Thursday 2004-12-16, filtering was removed. Shortly after the mailing list filtering policy was changed to "subscriber only". Apologies for the unwanted mail received during this period.
