Check if port 44158 is open:

C:\>curl ifconfig.co/port/44158

Traffic done after the initial synchronization : around 3.5GB/day so around 105 GB/month

After an Internet 10 minutes short outage, the UL/DL traffic catches up very slow - 2-3 hours. What is the mining impact?

Diagnostic report over Bluetooth

If the IP starts with 172.17.x.x, it is the Internal Docket container IP, not the one provided by the local network, you can ignore it.

How to find the Bobcat IP ?

1. Easiest way: Install Android app: Angry Port Scanner , scan for port 44158

2. other methods:

Look in the router
From Diagnostic Report window

Nslookup bobcatminer

C:\nslookup bobcatminer

Server: router.asus.com

Address: 192.168.x.y

Name: bobcatminer

Address: 192.168.z.v

In Windows, you can do this with:

for /l %i in (1,1,254) do ping -n 1 -w 50 192.168.0.%i

Basically, you are running ping in a 'for' loop. The arguments are thus:

/l -- causes 'for' to loop
%i -- incrementing variable
(start, increment, end) -- the start, increment, and ending values
-n -- number of packets to send
-w -- time in milliseconds to wait for a reply

After that completes, you can review the ARP table with

arp -a
