How do I block League of Legends? I have tried Web Content Filtering

[hcco]

I have tried Web Content Filtering in OpenDNS and it's still not blocked on my home network.

"

ALWAYS BLOCK:
leagueoflegends.com
na.leagueoflegends.com
play.na.leagueoflegends.com
pvp.net
lol.riotgames.com
lol.garenanow.com

It stopped blocking again today. We lost power yesterday for about 9 hours.....

Chances are big that in such a case your ISP has changed your IP address, and your IP address information may not have been updated at OpenDNS.  Did you ensure that you run an Updater and that this Updater does its job?
