I think most TO's aren't giving out the IPs during the online period to prevent any issues
in tier1 matches? ip's are not given
If I'm not mistaken, people can DDos matches using the IPs. So TOs don't release the IPs
Not possible most of the time.
Big tournaments keep the IPs private to prevent DDOS. However, many qualifiers will have the GOTV IPs posted on their HLTV matchpages so you can watch those in game if you like.
You have to go to esea and find the match ip’s
