Re: [atlas] contacing probe owner.

Quite the opposite IMHO, understanding that the anticipated means of communication will be email and that the email address of a probe's host will be generic, eg. <ripe-atlas-probe-[number]@atlas.ripe.net>, redirecting all incoming emails to a final address. The redirection would be configured via the portal then.

Using an address as described above would allow enumeration attacks. If it would use a hash instead it would be safer. The hash for probe XXX would be obtainable via the portal, where you would need to look up probe's details anyway. Geert Jan
