Route commands and usages

Dos command route
Command to manually configure the routes in the routing table


ROUTE [-f] [-p] [-4|-6] command [destination]
[MASK netmask] [gateway] [METRIC metric] [IF interface]

-f Clears the routing tables of all gateway entries. If this is
used in conjunction with one of the commands, the tables are
cleared prior to running the command.

-p When used with the ADD command, makes a route persistent across
boots of the system. By default, routes are not preserved
when the system is restarted. Ignored for all other commands,
which always affect the appropriate persistent routes.This
option is not supported in Windows 95.

-4 Force using IPv4.

-6 Force using IPv6.

command One of these:
PRINT Prints a route
ADD Adds a route
DELETE Deletes a route
CHANGE Modifies an existing route
destination Specifies the host.
MASK Specifies that the next parameter is the ‘netmask’ value.
netmask Specifies a subnet mask value for this route entry.
If not specified, it defaults to
gateway Specifies gateway.
interface the interface number for the specified route.
METRIC specifies the metric, ie. cost for the destination.

All symbolic names used for destination are looked up in the network database
file NETWORKS. The symbolic names for gateway are looked up in the host name
database file HOSTS.

If the command is PRINT or DELETE. Destination or gateway can be a wildcard,
(wildcard is specified as a star ‘*’), or the gateway argument may be omitted.

If Dest contains a * or ?, it is treated as a shell pattern, and only
matching destination routes are printed. The ‘*’ matches any string,
and ‘?’ matches any one char. Examples: 157.*.1, 157.*, 127.*, *224*.

Pattern match is only allowed in PRINT command.
Diagnostic Notes:
Invalid MASK generates an error, that is when (DEST & MASK) != DEST.
Example> route ADD MASK IF 1
The route addition failed: The specified mask parameter is invalid.
(Destination & Mask) != Destination.


> route PRINT
> route PRINT -4
> route PRINT -6
> route PRINT 157* …. Only prints those matching 157*

> route ADD MASK METRIC 3 IF 2
destination^ ^mask ^gateway metric^ ^
If IF is not given, it tries to find the best interface for a given
> route ADD 3ffe::/32 3ffe::1


CHANGE is used to modify gateway and/or metric only.

> route DELETE
> route DELETE 3ffe::/32

Command Purpose
add Adds a route.
change Modifies an existing route.
delete Deletes a route or routes.
print Prints a route or routes.

Route add

route add “destination” mask “subnetmask” “gateway” metric “costmetric” if “interface”

route add -p mask metric 2

In simple route add -p mask

Routes added by using the -p option are stored in the Windows registry under the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip \Parameters\PersistentRoutes

To delete the route to the destination with the subnet mask of, type:

route delete mask

To delete all routes in the IP routing table that begin with 10., type:

route delete 10.*

To change the next hop address of the route with the destination of and the subnet mask of from to, type:

route change mask

Netsh contexts
Netsh utility interacts with others using dynamic-link library files. Each Netsh helper DLL provides an extensive set of features called a context, which is a group of commands specific to this DLL networking component. These contexts extend the functionality of netsh. For ex., Dhcpmon.dll provides netsh the context and set of commands necessary to configure and manage DHCP settings.

For more information about Netsh contexts, use this command in the netsh shell:

netsh>show helper
DLL Filename Command
———— ——-
FWCFG.DLL firewall
IFMON.DLL interface
IPV6MON.DLL isatap
IPV6MON.DLL portproxy
RASMONTR.DLL appletalk
IPPROMON.DLL routerdiscovery
IFMON.DLL winsock
List of available netsh contexts
AAAA – commands for AAAA
Shows and sets the configuration of the Authentication, Authorization, Accounting, and Auditing (AAAA) database used by the Internet Authentication Service (IAS) and the Routing and Remote Access service.

DHCP – commands for DHCP
Administers DHCP servers and provides an equivalent alternative to console-based management.

Diag – diagnostic (diag) commands
Administers and troubleshoots operating system and network service parameters.

Interface – commands for Interface IP
Configures the TCP/IP protocol (including addresses, default gateways, DNS servers, and WINS servers) and displays configuration and statistical information.

RAS – commands for RAS
Administers remote access servers.

Routing – commands for Routing
Administers Routing servers.

WINS – commands for WINS
Administers WINS servers.
Displaying all of the adapter
To display all of the adapters in the computer with their current IP addresses to determine the correct adapter name, type the following command:

Netsh interface ip show config

Change static address to DHCP
To switch the specified adapter from a static address to DHCP, type the following command:

netsh interface ip set address “Local Area Connection” dhcp

Displays just the DNS server addresses
netsh interface ip show dnsservers

Displays the TCP connections
netsh interface ip show tcpconnections

Shows only TCP statistics
netsh interface ip show tcpstats

Displays the UDP connections
netsh interface ip show udpconnections

Shows only UDP statistics
netsh interface ip show udpstats

Change to a static address
netsh interface ip set address “Local Area Connection” static ipaddr subnetmask gateway metric

eg:- netsh interface ip set address “Local Area Connection” static 1

Dump all the network information
netsh dump

Import your IP settings

netsh -f c:\location1.txt or netsh exec c:\location2.txt

some examples

>netsh interface ipv4 show compartments

Enforce a system lock (screen saver lock)after a defined interval

It is possible to enforce a system lock after a defined interval. This requires the following two policy settings:
• Password protect the screen saver
• Screen saver timeout

using group policy preferences power plan is not a solution here ,as it is workgroup.

Local Group Policy Object (LGPO) that you can use to lock down settings on that machine. And if you have admin privileges on every machine in your workgroup, you can configure the LGPOs for your machines remotely from a single machine instead of having to walk around to each of them and log on locally.

To configure the LGPO on a remote machine, open a new MMC console, add the Group Policy snap-in, and click Browse to set the focus to a different machine than the local computer.

screensaver TS
Group Policy under/User Configuration/Administrative Templates/Control Panel/Display

Click “Start.” Type “Gpedit.msc” into the search box at the bottom of the Start menu. Press “Enter.”
Click “Yes” in the User Account Control prompt window, if one appears.
Navigate to the “User Configuration\Administrative Templates\Control Panel\Personalization” folder in the left pane of the Group Policy window.
Double-click the “Password Protect the Screen Saver” setting in the right pane of the Group Policy Editor window.
Click “Enabled.” Click “OK.”
Double-click the “Screen Saver Timeout” setting in the right pane.
Click “Enabled.”
Type the number of seconds you want to lock the PC after into the “Seconds” box. For example, type “600” if you want to lock the PC after 10 minutes.
Click “OK.”


The setting for the screensaver is in the path HKCU\ControlPanel\Desktop\ScreenSaveActive – a value of 0 switches off the Screensaver, while the value 1 turns it on.the screensaver is activated and is switches on after 10 minutes.
