Dynamic Port Range is used by the client computers (or a server acting as a client) to connect to Well Known Port Services or Root Services. A DNS Server is acting as a Server and listening on a specific Well Known Port (Port TCP and UDP 53). The Dynamic Port Range used by the client computers depend on the version of Operating Systems.
Port Range: 1024-65535
This port range is used by the computers running Windows XP, Windows 2000 Professional, and Windows Server 2003. A client computer running this version will always pick a port from the above mentioned Dynamic Port Range.
Port Range: 49152-65535
The Dynamic Port Range has been changed in the Windows Vista, Windows 7 and Windows Server 2008. By default, a fresh Windows Server 2008 installation will have this Dynamic Port Range configured. To see the port range, you can use the following commands:
- NetSh INT IPV4 Show DynamicPort TCP
- NetSh INT IPV4 Show DynamicPort UDP
To set or change the Dynamic Port Range:
- NetSh INT IPV4 SET DynamicPort TCP Start=1024 num=65535
- NetSh INT IPV4 SET DynamicPort UDP Start=1024 num=65535
Hi Nirmal,
I have query related to port range.
How do i check when was the port range changed, like if i run a netsh command and set the different value, where it will be logged?
Any command to check the same?
This is because i see on Windows 2016 i see port range is changed to “start port: 1025 “, not sure how (which application or GPO setting or anyone running command manaully) its changed?
thanks for your help.
Thanks,
Deepak
