What makes you ask that? I don't know a lot about netstat at this stage but I can read domain names and I can see that you have local connections (your computer is called julius, I'm guessing). Also, there are connections to cnet.com, cnet.co.uk, mozilla.com and this one which is a Google domain, 1e100.net.
http://superuser.com/questions/75841/what-is-1e100-net-and-why-do-i-have-tcp-ports-open-to-it

When you have a look at the log, you can see various addresses such as this one, c18-gdl-xw-lb.cnet.com, which has cnet.com at the end - that's the domain. Likewise, c16-uk-cnetnetworks-lb.eu.cnet.co.uk has cnet.co.uk at the end.

revsci.net is an ad server. You can block that.

llnw.net is Limelight Networks and is probably no concern:

The only two I'm having much trouble with are the IP addresses, but I think they both belong to Akamai:

http://whois.domaintools.com/84.53.132.42
http://whois.domaintools.com/84.53.178.88

Here is a Wiki article about netstat:

And if you have genuine reason to worry about whether your computer has any problems of a security nature, there are two very good guides here, one to clean an infected computer and the other one to check if you have put sufficient security on your computer:
