How to validate IP address using Robot Framework

Example: 192.168.101.12

Conditions:

1. Number of characters
2. String should not exceed 15 characters
3. Allow only numeric characters

you can use regex to validate the ips.

import re

def isValidIp(ip):
    pattern = "((\d{1,3}).(\d{1,3}).(\d{1,3}).(\d{1,3}))"

    if re.match(pattern, ip):
        return True
    else:
        return False

test:

test = ["123.123.123","randomstring","123.a54.12","1234.12.1111"]

for item in test:
    print(isValidIp(item))

True
False
False
True

Builtin library has a keyword for matching regexes. You can use Should Match Regexp to validate the ip. Here is an example I made with a regexp from this answer

***Variables***
${correct_ip}    192.168.101.12
${false_ip}      999.999.999.999
${ip_regexp}      ^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$
*** Test Cases ***  
test 
    Should Match Regexp    ${correct_ip}    ${ip_regexp}
    Should Not Match Regexp    ${false_ip}    ${ip_regexp}
