Valve Owned Domains

[GZ]

A lot of people seem to be falling for the steam gift phishing sites this year, so I'm trying to put together an anti-phishing guide for my community and was wondering if this domain list I found in a quick google search is still valid:
deathmatchclassic.com
modexpo.com
poweredbysteam.net
steamcommunity.com
steamdevdays.com
steamgames.com
steamgames.net
steampowered.com
steampoweredgames.com
steamserver.net
steamstatic.com
steamusers.com
steamusers.net
valve.net
valvecorporation.com
valvesoftware.com
of course the guide only needs those with a steam login tied to it I just wanted to make sure I didn't miss any that would have a steam login on it. when I'm done with it I can post it here too as I'm sure my community is not the only one getting affected. thanks for your time guys!

Just tell, only log in on steams community site directly.
Reduce it to the most common ground. No one remembers all these links.

I'm not going to use all of them only the ones that have a login tied to it. so far the short version is steamcommunity.com and steampowered.com gotta have steampowered too as that has the store. I guess I coulda asked about just those 2, but I wasn't done checking the whole list for domains I don't use but others may.
