[atlas] New measurement target suggestion: 6to4 anycast

Hello,

Please inform me your decision about this interesting matter:

>> I'd like to suggest adding to the list of monitored addresses a new one:
>>
>>   192.88.99.1 - 6to4 anycast IPv4 to IPv6 gateway;
>>
>> This could provide interesting data on what percentage of networks
>> have this address blocked/inaccessible (resulting in broken
>> operation of 6to4), and also what is the average latency to the
>> closest 6to4 gateway across various countries/regions.
>>
>> The next step would possibly be the collection of statistics which
>> ASes 'see' whose 6to4 gateways, this can be inferred from the AS of
>> the traceroute hop that is right before the 192.88.99.1 on the trace.

> It seems that there is interest for doing this measurement, so we'll
add it to the list -- most likely in January, after the holiday break.

Maybe we'll see some interesting results before June 6. Could you add
it, please?
