Given a valid (IPv4) IP address, return a defanged version of that IP address.A defanged IP address replaces every period "." with "[.]". Example 1:Input: address = "1.1.1.1"Output: "1[.]1[.]1[.]1"Example 2:Input: address = "255.100.50.0"Output: "255[.]100[.]50[.]0" Constraints:The given address is a valid IPv4 address.
Question
Given a valid (IPv4) IP address, return a defanged version of that IP address.A defanged IP address replaces every period "." with "[.]". Example 1:Input: address = "1.1.1.1"Output: "1[.]1[.]1[.]1"Example 2:Input: address = "255.100.50.0"Output: "255[.]100[.]50[.]0" Constraints:The given address is a valid IPv4 address.
Solution
Here is a step-by-step solution in Python:
- Define a function that takes an IP address as an argument.
def defangIPaddr(address):
- Use the built-in
replace()function in Python to replace every period "." with "[.]" in the given IP address. Thereplace()function takes two arguments: the character to be replaced and the character to replace it with.
return address.replace('.', '[.]')
- Call the function with an IP address to test it.
print(defangIPaddr("1.1.1.1")) # Output: "1[.]1[.]1[.]1"
print(defangIPaddr("255.100.50.0")) # Output: "255[.]100[.]50[.]0"
The complete code is:
def defangIPaddr(address):
return address.replace('.', '[.]')
print(defangIPaddr("1.1.1.1")) # Output: "1[.]1[.]1[.]1"
print(defangIPaddr("255.100.50.0")) # Output: "255[.]100[.]50[.]0"
Similar Questions
A valid IP address consists of exactly four integers separated by single dots. Each integer is between 0 and 255 (inclusive) and cannot have leading zeros.For example, "0.1.2.201" and "192.168.1.1" are valid IP addresses, but "0.011.255.245", "192.168.1.312" and "[email protected]" are invalid IP addresses.Given a string s containing only digits, return all possible valid IP addresses that can be formed by inserting dots into s. You are not allowed to reorder or remove any digits in s. You may return the valid IP addresses in any order. Example 1:Input: s = "25525511135"Output: ["255.255.11.135","255.255.111.35"]Example 2:Input: s = "0000"Output: ["0.0.0.0"]Example 3:Input: s = "101023"Output: ["1.0.10.23","1.0.102.3","10.1.0.23","10.10.2.3","101.0.2.3"] Constraints:1 <= s.length <= 20s consists of digits only.

5. Define IP Address. Specify IPv4 address classes with their address ranges. [1+4]
An IP address is represented by a series of numbers segregated by periods(.).An IP address is the identifier that enables your device to send or receive data packets across the internet.IP address is generated mathematically and assigned by the IANA (Internet Assigned Numbers Authority).IP addresses are permanent and never change.IP addresses are not produced randomly.
