This is very nice. Thanks! I think it's important to note specifically that the changed: attribute cannot be altered either in order for a delete to be accepted, since this is counter-intuitive for some folks (uh, me ;-). Selina

A number of you have had problems when you tried to delete an object from the RADB. Here is a brief tutorial on the subject. If you have additional questions, please send a note to db-admin@ra.net.

How to Delete Objects from the RADB

Internet Service Providers (ISPs) and network operators will often need to delete Route objects, AS objects, or Maintainer objects from the RADB. You'll need to delete a Route object (and submit a new one), for example, if:

--You are changing ISPs and need to change the origin AS (Home AS) for your route --You are no longer using a particular route prefix --You are moving to a larger aggregate and want to delete a more specific prefix

If you want to change any of the following attributes, you'll first need to delete the object, and then re-submit the corrected one:

Object Field ----- ----- Route route: origin: AS aut-num: Maintainer mntner:

Follow these instructions to delete an object from the RADB:

1. Use the whois tool to get a copy of the object exactly as it currently exists in the registry. Put the object in a temporary file. For example:

whois -h whois.ra.net 10.1.2.0/24 > temp

2. Edit the 'temp' file you've created. If the file contains more than one object, remove the extra objects so that only the object or objects you want to delete remain.

3. Do not change any lines in the object(s) you want to delete. Simply append a line such as the following to the objects:

delete: user@your.net <reason for the deletion>

To delete more than one object, append a 'delete:' line to each object and separate each object by a blank line. Your 'temp' file might then look like this:

route: 10.1.2/24 descr: Example-NET origin: AS0 mnt-by: AS0-MNT changed: pern@Example-NET 950525 source: RADB delete: user@your.net prefix no longer used

route: 10.1.3/24 descr: Example-NET origin: AS0 comm-list: COMM_NSFNET advisory: AS690 1:701(136) 2:701(134) 3:1800 mnt-by: AS0-MNT changed: pern@Example-NET 950525 source: RADB delete: user@your.net prefix no longer used

4. Submit the object to auto-dbm@ra.net. For example:

mail auto-dbm@ra.net < temp
