I have a requirement where we have to send requests with different/unique IP's and can we set 5000 unique IP's and send through JMeter.
You can set the source IP address for the request under "Advanced" tab of the HTTP Request sampler
The tricky point is that the IP address (or its alias) must exist on the operating system level so the steps you need to take are:
Assign 5k IP addresses (or aliases) to your network interface(s), refer your operating system documentation for details on how this could be done
Put these addresses into a CSV file
Use CSV Data Set Config so each thread could get the new IP address from the CSV file on each iteration
Use the variable from the CSV file in "Source address" field of the HTTP Request sampler
That should be it

In the scenario where you're running a single Linux instance of jmeter with 20000 threads and 4 ip addresses, would jmeter (HttpClient4) use all ports in all 4 IP addresses for http connections, or is it restricted to one IP choosen by jmeter (In Linux machine) ?
Thanks
JMeter will stick to a single IP address by default, if you want to distribute the outgoing connections between all 4 IP addresses you will need to put them into a CSV file and use CSV Data Set Config to read it so each thread (virtual user) would choose a new source address on each iteration.
The source IP address can be set at "Advanced" tab of the HTTP Request sampler (or HTTP Request Defaults)
See Using IP Spoofing to Simulate Requests from Different IP Addresses with JMeter article for more information.
I am trying to invoke distributed load testing with jmeter (Which have 3 ips in it) and it is running in only one ip. Will other ips also run in the background or they won't even start?
If you have a Distributed JMeter Test architecture with 1 master and 3 slaves my expectation is that each JMeter slave has its own IP address so you should see requests coming from 3 different IPs to the system under test.
If you need to mimic more IP addresses - there is "Source address" section which lives under "Advanced" tab of the HTTP Request sampler where you can specify the desired outgoing IP address.
But be aware that the IP address (or its alias) must exist on the operating system level in order to be used at this field so you need to ensure that all source IP addresses you're going to use exist and are usable by JMeter.

I am trying IP spoofing in JMeter HTTP requests but my public IP is going to the request, not the IP address which I have specified under advanced option in HTTP sampler. can anyone help me in this?
I am also sharing the screenshot of my test plan.
here
In my test plan my let's say my IP is x.x.x.x and the IP which I have configured for IP spoofing is: 192.168.23.12 as shown in the screenshot but request to the server is still going with my IP which is x.x.x.x.
Can anyone help me out in this?
As per HTTP Request sampler documentation
Source address field [Only for HTTP Request with HTTPClient implementation]
So change "Implementation" to HttpClient4 and it should start working as expected.
Also be aware that you need to have this IP address (or alias) defined in the underlying operating system.
See Using IP Spoofing to Simulate Requests from Different IP Addresses with JMeter article for more information and configuration instructions for different operating systems.
Please check the below test plan:-
When source address field is empty, all runs fine. When I put in an IP, even if it is my actual IP, I get an error:
Response code: Non HTTP response code: java.net.SocketException
Response message: Non HTTP response message: Network is unreachable: connect
I run Windows... Also I have already tried all the Implementations.
There should be few pre-requisites met:
You need to have HTTPClient implementation (see HTTP Request sampler documentation)
Source address field[Only for HTTP Request with HTTPClient implementation]
In case of single IP address:
The IP address needs to be available in the underlying operating system, it may be either IP associated with NIC or an IP alias
Relevant Source address type needs to be specified, in case of single IP it should be IP/Hostname
See Using IP Spoofing to Simulate Requests from Different IP Addresses with JMeter guide for more detailed information on the domain.
Is there any way for IP Spoofing in jmeter.i have tried it by "CSV data set config".Is there any other way..please let me know.Thanks in advance.
Following steps will help you implement the IP Spoofing:
Request for 6 static IP address (it depends on your requirement) from your IT team.
Go to IPv4 properties, add the primary IP, Subnet mask, Gateway, DNS etc.
Click on advanced button, in IP Address section add all the remaining IP address.
Save all the 6 IP address in a CSV file
Now open Jmeter, add a CSV data set config (at the top below Test Plan)and configure IP address CSV file in it
Click on your HTTP samplers 1 by 1 and change the below mentioned value as per your CSV Data Set Config
Note: Spoofing will not work using Wifi. The Jmeter machine must be connected to LAN to achieve IP Spoofing.

Hope this will help.
Yes, you can send request using multiple Ip addresses to your application something like real world scenario.
Please check following :
Use IP spoofing in jmeter
You will have to use HTTPClient implementations.

First we need to create the virtual IP Enter the command in Terminal
ifconfig
go to root folder by:- sudo su
suppose you want a series of 10.0.0.1~10.0.0.255 then run the blow command :-
for each in $(seq 1 254); do ifconfig eth0:$each 10.0.0.$each; done
Print your IPs:- for each in $(seq 1 254); do cat 10.0.0.$each > ip.txt; done
for each in $(seq 1 254); do echo "10.0.0.$each"; done > ip.txt
After generating the reports run this command :- for each in $(seq 1 254); do ifconfig eth0:$each 10.0.0.$each; done
do :- ifconfig and check that IPs are assigned to every eth port
Now open your Jmeter create a thread user add CSV Data Set Config, Add HTTP Request Sampler, Add Listner according to you
enter image description here
give the path of saved csv file which is containg your virtual IPs and your Variable name like this in below imageenter image description here
Now give your IP or host address of your software, give the port number, give the API address which you want to test and body of your POST data if any
Now give your variable name in advance tab like this ${Variable_name_given_in_CSV Config Element} and Click on Run button it will hit you API with multiple virtual IPs [enter image description here][3]
