sed replace pattern

I have a file with multiple lines, all in the same format. For each line, I need to replace the sequence of digits after the last : with a new value, but keep the single quote at the end of the line.

Example:
Input: ( two lines of file)
Code:
Name: 'text1:200/text2:1.2.3.4'
Name2: 'text3:200/text3:1.2.3.17'


New Value to use instead of 1.2.3.4:
Code:
1.2.3.x or 4.5.6.7 ( the first 3 digits don't always match)

Output:
Code:
Name: 'text1:200/text2:1.2.3.x'
Name2: 'text3:200/text3:1.2.3.x'

Can I use sed to do this?
Even if I can just replace the last digit(4) after the last dot with a new value (x) that would work for now....

Thanks!
