Hi,


Did the authors consider images to explain certain concepts? For example
bit boundary? RIPE NCC can help with that, if you wish.

Should we? Isn't teaching the subnetting a little bit out of the scope of this document? Or would you like to replace the existing attempts to show the nibble boundaries in the document?

Cheers and thnx, Jan

Don’t know. I like plain-text docs because they are light-weight to download, but I am a visual learner myself (a picture says more than a thousand words). 
Also, because some readers might not be too familiar with English, a picture might help. 

I would suggest a picture for 
-nibble boundaries

Highlight in bold the differences in:

2001:db8:aaaa:1a00::/56
2001:db8:aaaa:1b00::/56
2001:db8:aaaa:1c00::/56

2001:db8:aaaa:1d00::/56 


and

2001:db8:aaaa::/48
2001:db8:aaab::/48
2001:db8:aaac::/48

2001:db8:aaad::/48

But that is basically it, now that I read it back. Maybe others have suggestions for this?

Like I said, the doc works without images, but it might help. 

 Cheers,

Nathalie
