As a result, the node map on DigiStats indicates that there are 14 active nodes. But, it's not accurate. It's not fully implemented. There are way more than 14 active nodes. It's hard to say exactly how many nodes there are right now ... but the number was right around 3000, or slightly higher.
screenshot, tcp-connection-list, ip-list ... something which confirms this.
A node is someone with an open wallet that has the full blockchain downloaded, which can communicate with other wallets.
Here's one way to get a list (it won't be a complete list of all nodes).
Open the core wallet. Leave it open for awhile. The longer you do, the more nodes you will get.
I opened mine for an hour and got 51 nodes. (Not everyone keeps their wallet open all the time, and you aren't going to communicate with all of them that are currently open).
When you have waited as long as you want, go to your digibyte data directory. It should be c:/users//appdata/roaming/digibyte
There will be a file called debug.log
In that file will be a bunch of data about blocks and such, several lines will look like this:
2015-07-03 11:55:46 receive version message: /DigiByte:3.0.3/: version 70002, blocks=987677, us=(your IP), them=73.198.40.189:12024, peer=73.198.40.189:12024
All you need to do is sort out these lines and count how many "them" IP addresses are unique.
