# Cisco DNA IPv4 Address Conflict Prevention

This Python script will verify if the use of an IPv4 Address will create a duplicated IPv4 address.

**Cisco Products & Services:**

- Cisco DNA Center

**Tools & Frameworks:**

- Python environment

**Usage**

This sample script will:
- ask user to input the file name with the CLI template to be configured
- validate the provided file name exists
- open the file
- select the IPv4 addresses to be configured on interfaces
- validate if the selected IPv4 addresses are valid IPv4 addresses
- Verify if the IPv4 addresses are:
- Used by a network device
- Used by a client
- Reachable
- deploying the configuration template will create an IPv4 address conflict if any of the above validations fail for one IPv4 address

Execute the script:

$ python ip_conflict_prevention.py

*Sample output:*

Start of Application "ip_conflict_prevention.py" Run
Input the CLI Template file name (example - "config.txt"): cli_template.txt

The CLI template:

!
interface Loopback65
ip address 10.93.130.21 255.255.255.255
!
interface Loopback200
ip address 10.93.141.67 255.255.255.255
!
interface Loopback201
ip address 10.93.140.35 255.255.255.255
!
interface Tunnel201
ip address 10.93.130.19 255.255.255.252
tunnel source Loopback200
tunnel destination 10.93.140.48
keepalive
!
router eigrp 123
network 10.93.140.49 0.0.0.0
!
router eigrp 201
network 10.93.140.46 0.0.0.0
redistribute static route-map REMOTE_ACCESS
exit
!

The CLI template will configure these valid IPv4 addresses:
['10.93.130.21', '10.93.141.67', '10.93.140.35', '10.93.130.19']

The IPv4 address 10.93.130.21 is used by this device PDX-M , GigabitEthernet0/0

The IPv4 address 10.93.141.67 is used by this device AP682C.7B4C.0510 ,

The IPv4 address 10.93.140.35 is not used by any network devices
The IPv4 address 10.93.140.35 is used by a client

The IPv4 address 10.93.130.19 is not used by any network devices
The IPv4 address 10.93.130.19 is not used by a client
The IPv4 address 10.93.130.19 is not reachable

Deploying the template config.txt will create an IP address conflict

End of Application "ip_conflict_prevention.py" Run

Process finished with exit code 0
