Update Relay Node Map
How to produce an up-to-date map of the current distribution of relay nodes
From a Linux or a Linux-compatible box, use the
dig command to query the algobootstrap service on mainnet.algorand.network for its records. To do this run the following command:
dig _algobootstrap._tcp.mainnet.algorand.network SRV +short
This produces a list of uniquely named targets of the form
r-xx.algorand-mainnet.network, where xx is a pair of alphanumeric characters. These names can be resolved to standard DNS names and IP addresses using
dig again. For example, the target r-y1.algorand-mainnet.network can be resolved as follows:dig r-y1.algorand-mainnet.network +short
Note: Not all targets have proper DNS names, and a target may resolve to multiple IP addresses. For example, the above command produced the output:
mr-cdg-1aa0.rnr.algonode.net.
108.61.176.51
104.238.188.119
Repeat this step for each of the named targets to resolve the entire list of targets and collect the resulting list of IP addresses in a file, say
relay_nodes_ips.Use ipinfo.io (or a similar service) to generate the corresponding location metadata. For instance, using ipinfo.io, the following command (where
<TOKEN> is a secret you obtain by registering for free at ipinfo.io) saves location metadata for each IP in the list relay_nodes_ips in JSON format in a file called locations.json:cat relay_nodes_ips | curl -XPOST --data-binary @- "ipinfo.io/batch?token=<TOKEN>“ > locations.json
Extract from the retrieved JSON a list of latitude/longitude location information (using the handy
jq command for processing JSON):jq -r '.[] | .loc | select( . != null )' locations.json
Import the resulting list at some mapping service, such as mapcustomizer.com or mymaps.google.com, to generate a map of relay node locations.
