Wireshark can automatically resolve these IP address to domain names, although this feature isnt enabled by default. These names are often used interchangeably which can lead to some confusion: A configuration that uses the SSL protocol (SSLv2/SSLv3) is insecure. You can check and find the proper one via $ ip link. Check the issuer data for both IP addresses to find the data listed below. By default port 1433 is not interpreted as having TLS; the default for TDS is to be unencrypted. WebWireshark is a network protocol analyzer, or an application that captures packets from a network connection, such as from your computer to your home office or the internet.

If we start looking through these packets we come across something very interesting in unencrypted, plain text. You are viewing a connection which uses MS-TDS ("Tabular Data Stream Protocol"): If you view the TDS protocol documentation, it specifies that the SSL packets are encapsulated within a TDS wrapper: In the Microsoft Message Analyzer screencap you posted, we can see the TDS header (boxed in Red, starts with 0x12), followed several bytes later by the TLS CLIENT_HELLO packet (boxed in Blue, starts with 0x16 0x03 0x03): 0x03 0x03 is the TLS version (TLS 1.2, as per RFC 5246): The version of the protocol being employed.
