IPv6 compression

fritzelly

Not sure where best to put this question...

I'm doing a Google Coursera course and totally stuck on an assignment for IPv6 compression

Here's a couple of the questions and what I think the answer is using the two rules of compression but they're both wrong

Can someone point out what I'm doing wrong thanks

Q 8​b​f​a​:​9​9​f​0​:​d​4​c​5​:​0​b​8​c​:​0​f​6​f​:​0​4​d​f​:​2​8​0​4​:​2​8​3​d​

A 8​b​f​a​:​9​9​f​0​:​d​4​c​5​:​​b​8​c​:​​f​6​f​:​4​d​f​:​2​8​0​4​:​2​8​3​d​

Q 0​0​e​b​:​0​0​0​0​:​0​0​0​0​:​0​0​0​0​:​d​8​c​1​:​0​9​4​6​:​0​2​7​2​:​0​8​7​9​

A ​e​b​:​:​d​8​c​1​:​9​4​6​:​2​7​2​:​8​7​9​

Dont think you can omit leading zeros, only blocks of four

I guess the exam is banjaxed then - will contact them, thanks

Actually I've just inspected the field and it should be 39 characters long so must be some JS or something blocking any more than 20 characters
