Yes you can. I have 3 instances on my development PC.

To connect to an instance in SSMS, use ServerName\InstanceName

yes. I have installed named instance on same server which was already installed default instance MSSQLSEVER on that server.

After installed Both instances are connected with SSMS.

Default Instance - sllways connect default TCP/IP port 1433.

Named Instance - allways connect UDP port 1434

both are managed by SQL Browsing services.

Configuration manager->Network configuration -> TCP/IP protocol

Physical IP concfigured at IP2 and then UDP Port number not available. it showing such as use dynamic port - 0., IPAll column showing dynamic port -64954.

thanks

In Default instance showing like this

USE master

GO

xp_readerrorlog 0, 1, N'Server is listening on', 'any', NULL, NULL, N'asc'

GO

Server is listening on [ 'any' <ipv6> 1433].

Server is listening on [ 'any' <ipv4> 1433].

Server is listening on [ 'any' <ipv6> 1434].

Server is listening on [ 'any' <ipv4> 1434].

Named Instance showing like this

Server is listening on [ 'any' <ipv6> 64954].

Server is listening on [ 'any' <ipv4> 64954].

But here named instance not using UDP port 1434

thanks

No it wont use UDP 1434, thats the browser port.

The whole part of the browser is that it diverts the traffic to the correct ports, so you dont need to worry about it, as your not always going to get the same port for the same instance, they are dynamic, unless you configure it otherwise.
