RIPE Whois Database maintenance
by Engin Gunduz 28 Dec '04

28 Dec '04

Dear Colleagues Apologies for any duplicate mails On Wednesday, 29 December 2004, we will perform maintenance on the RIPE Whois Database. After this, the RIPE Whois Database will support RPSLng. You can find more information about this at: http://www.ripe.net/db/news/rpslng-211204.html We plan to start the maintenance at 15:00 Amsterdam time (14:00 UTC). It will take around four hours. During this time, there will be no interruption to Whois queries, however: - You will not be able to make any updates to the Whois Database using either webupdates or the LIR Portal, - We will process any e-mail updates, sent to auto-dbm(a)ripe.net, after we complete the maintenance work. We apologise for any inconvenience this work might cause. Best regards Engin Gunduz RIPE NCC Software Engineering Department

RPSLng in the RIPE Whois Database
by Shane Kerr 21 Dec '04

21 Dec '04

Dear Colleagues, Beginning Wednesday 29 December 2004, the RIPE Database will support RPSLng. RPSLng extends the Routing Policy Specification Language (RPSL) allowing description of IPv6 and multicast routing policies. It includes a new object type, ROUTE6, and new attributes, such as "mp-import:" and "mp-export:". RPSLng was submitted to the IETF to become an RFC. You can read the most recent draft at: http://www.radb.net/rpslng-08.html This change will not affect the current contents of the database. It is optional for any objects you maintain. The main differences for query users are as follows: - Currently a query for an IPv4 address or network may return INETNUM, ROUTE, and INET-RTR objects. A query for an IPv6 address or network can only return an INET6NUM object. After we put RPSLng into production, IPv6 queries will start to also return ROUTE6 and INET-RTR objects, if they are in the database. - Currently an inverse query (using the "-i" flag) for AUT-NUM objects may return ROUTE objects. After we put RPSLng into production, a query will return both ROUTE and ROUTE6 objects. If you want to limit your query, you can use the "-T" flag. For example, if you only want ROUTE objects returned to an inverse query, you can type: whois -h whois.ripe.net -T route -i origin AS3333 Please change your scripts if necessary. We will not move the contents of the RPSLng prototype Whois server to the RIPE Whois Database. You will have to create any objects that define your routing policy in the production RIPE Whois Database. You can update the RPSLng prototype Whois server until the start of January 2005. The query interface will be available until the end of January 2005. -- Shane Kerr Software Manager RIPE NCC
