80 is http for html webpages. 443 is for Adobe flash.
So, that looks just like normal web browsing to me... But, I
didn't go through check the IPs. You might want to memorize some
of the commonly used port numbers too, e.g., email, ftp, telnet,
http, nntp, pop3, flash, etc. Then, you can recognize attempts to
connect to non-standard ports, i.e., more likely to be an attack
or port scan.
From the number of connections, it looks like perhaps a few
webpages were opened... Sometimes the connections to IPs stay
"ESTABLISHED" long after you've closed a webpage and even after
you've closed your web browser. I'm not sure what OS you're
using, but instead of displaying the IPs, display the DNS names
for them. Use "netstat -a" instead of "netstat -an". In fact, go
ahead an look the DNS with "nslookup" or others like "dig" or
"host". Your OS should have a command to allow you to look up DNS
names. Some older OSes don't though. You can try the link below
if you don't have a DNS lookup application. If it's web browsing
related, you'll see lots of major sites related to your browsing
activity. E.g., if you go to Yahoo, you'll see a bunch of Yahoo
sites, plus Adobe for Flash, plus a bunch for advertisement
servers, etc. Sometimes, various Yahoo and Google sites link to
Facebook and Twitter too.
