Dear all,

The RIPE Atlas team have added a number of new measurement options on RIPE Atlas. Here’s an overview of the changes:

• DNS measurements
  
  
• timeout: allows the user to specify a custom timeout in milliseconds after which probes will stop waiting for a response from the DNS server
  
  
• use_macros: allows the use of special macro strings in the "query_argument" field, to create unique or easily distinguishable queries. The allowed macros are:
• $p  the (integer) ID of the probe carrying out the measurement
• $r   a random 16-digit hexadecimal string
• $t   a Unix timestamp of the time that the probe carries out the DNS query
  

• SSLcert measurements
  
  
• hostname: specifies a hostname to send as a Server Name Indication (SNI), which is necessary for web servers which host multiple TLS domains on the same IP address.
  

• Ping measurements
  
  
• include_probe_id: include the probe ID as an ASCII string within the payload of ping measurements. Note: this is included in addition to other payload data.
