Backlinks from addon domain, do i need to disavow it?

i have a site, its have multiple domain, like google.com, google.ca, google.in, etc

google.ca & google.in are linked to google.com, and looks like google.com got penalty, its hard to get page one in the last 1 year

what is your suggestion, should i disavow google.ca & google.in?


NB.
- google.com, google.ca, google.in are just example, you can use mydomain.com, mydomain.ca, mydomain.in instead

- the content of each addon domain are different & unique

This is not any big issue. You have got unique contents with each site, so there will be no much impact.

because already one year the mydomain.com is kicked to rank #400 or nowhere in the serp for main keyword

i checked in webmaster tools, from mydomain.ca & mydomain.in, its get about 8.000 backlinks each, google looks like consider it as spam backlinks & penalties mydomain.com?
because its addon domains, them all have same ip & same server


help please

So the IP address is the same, the same thing happens using a shared hosting accounts with the same host or a resellers account. If you have completely different sites all linked to each other I've never heard of anyone being penalized for it!

But, I also have a good news to share with you that some one who disavowed all his addon domains got the ranking back.
