Here are some free network tools and information sources that I either use, like, or think are cool:
- speakeasy.net - Is it just me or is this computer slow? My favorite internet speedtest site. There are several good speedtest sites out there, I happen to like this one.
- WhoIs.net - Again, there are a bizzilion WhoIs sites out there, this one seems as good as any. What I like about it mostly is it isn't GoDaddy. GoDaddy sucks. They really do, on many levels.
- WooRank - not a bad website analyzer. they try to get you to pay for more advanced features, as does every other site I've found that provides this type of service.
- PCnames - Another good domain check engine.
