TCP Max Segment Size (MSS) is another parameter of the three-way handshake in your network trace that means you'll find the data you need in the SYN - SYN/ACK packet. Here are the steps to take to filter your Netmon to get the IP address (and take a look at DNS Latency). This example uses outlook.office365.com, but may also use the URL of a SharePoint tenant (hithere.sharepoint.com for example).

To see how long the authentication is taking, add the Time Delta column. Microsoft's Network Monitoring tool (Netmon) analyzes packets (network traffic) that passes between computers on networks. Because the actual body of the traffic is encrypted, that is, it travels on port 443 via SSL/TLS, you can't read the files being sent.
