Does anyone know about the Bitnodes crawlers from these addresses:

54.173.72.127 (ec2-54-173-72-127.compute-1.amazonaws.com)
54.183.64.54 (ec2-54-183-64-54.us-west-1.compute.amazonaws.com)
54.194.231.211 (ec2-54-194-231-211.eu-west-1.compute.amazonaws.com)
54.66.214.167 (ec2-54-66-214-167.ap-southeast-2.compute.amazonaws.com)
54.67.33.14 (ec2-54-67-33-14.us-west-1.compute.amazonaws.com)
54.77.251.214 (ec2-54-77-251-214.eu-west-1.compute.amazonaws.com)
54.94.195.96 (ec2-54-94-195-96.sa-east-1.compute.amazonaws.com)
54.94.200.247 (ec2-54-94-200-247.sa-east-1.compute.amazonaws.com)

They appear to have started around the same time so they may be operated by the same owner. If you are the owner of these crawlers, please consider running only one instance of the crawler to avoid taking up the available connection slots on each node.

Does anyone know about nodes from 178.63.66.130 and 5.196.64.92?

https://getaddr.bitnodes.io/nodes/1417567189/?q=178.63.66.130
https://getaddr.bitnodes.io/nodes/1417184424/?q=5.196.64.92

They account for 10% of the network of reachable nodes at the moment.

An interactive visualization of all reachable nodes in the Bitcoin network is now available from https://getaddr.bitnodes.io/nodes/network-map/.

The nodes are grouped by ASN. Each ASN is allocated a 64 by 64 square on x-z plane with its y axis from 0 to 160. Each node has a (x,y,z) point relative to its ASN based on its 32-bit (IPv4) or 128-bit (IPv6) IP address in integer value. ASNs are populated from inner to outer layer of the grid according to the number of nodes in descending order.

Click on the colored circle to filter nodes by state or a square to highlight nodes in the ASN.

1) Go to https://getaddr.bitnodes.io/.
2) Click on the count to access the list of reachable nodes.
3) Search for your node and click on it to activate its status page.
4) Add a contact information to receive an alert when your node goes down or becomes unreachable.

Hey guys, do we have a mirror of bitcointalk.org? I recall someone brought up the idea of mirroring and allowing search there. The current search is too restrictive. Google's site:bitcointalk.org <QUERY> works as expected but its incomplete and delayed by days or weeks.

Hi folks,

As part of my attempt to learn more of the Bitcoin protocol and also to get at a rough estimate of the current size of the Bitcoin network, I've started working on https://github.com/ayeowch/bitnodes.

The project is essentially a Python script that sends out getaddr (https://en.bitcoin.it/wiki/Protocol_specification#getaddr) message to all peering nodes in a recursive manner to find all the nodes in the network. It is far from complete as I have yet to arrive at a final number myself but I am sending this out anyway to get more feedbacks and also to share with those that may be interested on this metric as well.

Hi guys,

Is the relay field (bool/1 byte) required in all version packets coming from client with protocol version >= 70001 or my interpretation of https://en.bitcoin.it/wiki/Protocol_specification#version is incorrect?

Has anyone been able to get the number of active nodes in the entire Bitcoin network?

There were some effort made in this area a while back but no recent/updated data:
1) https://bitcointalk.org/index.php?topic=2346.0 (https://smsz.net/btcStats/bitcoin.kml) - no longer updated
2) http://bitcoinstatus.rowit.co.uk/ - no longer updated
3) http://www.bitcoinmap.com/ - no longer updated
4) http://www.weusecoins.com/globe-bitcoin/ - gone

Blockchain.info has this but only shows nodes that they are/were connected to:
