Since the connection established before we started to capture the packets, We were not be able to capture the dns resolution packets, in other saying we missed to capture some dns packets that is why Wireshark can not translate some IP addresses into domain names. Remember that we selected “ use captured DNS packet data for address resolution” from Edit->Prerences->NameResolution. In the end, you will see something like below.Īs you see in the figure above, the IP address that is using most of the bandwidth is not translated into a domain name. Next, click Ok to close the window.ĥ) Again from Statistics menu, click on In the opening window, do not forget to select “Name Resolution” and sorting based on the parameter you want. Select “Name Resolotion” from left pane then check “ use captured DNS packet data for address resolution” and “ use an external name resolver”. From Edit menu, click on the Preferences as below.Ĥ) Preferences window pops up. 1 byte is equal 8 bits.ĪLSO READ: How to analyze IPsec Traffic with Wiresharkģ) You should enable name resolution, if the IP addresses in the figure above are not familiar to you. Since the file size and bandwidth rate are in different units, you need to calculate your file size in bits. Let's assume that you have a file size of 1.8GB (gigabytes) to transfer it to your Dropbox and you would like calculate how much time it will take for transferring the file. when you buy a service of 30Mbps (megabits per second) from your ISP (Internet Service Provider), it means you will be able to transfer 30 million bits in a second. We will find the answer in this article, using many functionality in Wireshark.īandwidth is the maximum rate of transferring data from one point to another point in a specific amount of time. Each time there were discrepancies and he was asking for a solution. Tools like Cacti, Net Limiter, Resource Monitor and Task Manager were used during the test. According to his post on the site, he tried many methods but was not happy with the different results, since he expected similar outcomes for bandwidth usage. A user was asking how to measure his real bandwidth. I came across a question about bandwidth measurement on. Finding the culprit eating your bandwidth.
