Query on IP connections & security

[AG <computing.account@googlemail.com>]

I was going through the hardinfo application and when I got to "IP 
connections" I noticed the following connections have the "Established" 
status using TCP and both on port 443 (SSL and HTTPS).

One of these connections is to 71.62.0.176 (which doesn't seem to have a 
listing in the whois database that means anything) and 88.169.124.190 
which points to http://www.proxad.net according to whois

What applications could I have on my machine that would establish tcp 
connections with either of these using ssl/https?

Also, although I was under the impression that the portmap service was 
not enabled at boot up, it would appear that it is running in the 
background.  I recall that portmap used to be a security risk, but is 
this still the case and should I be concerned?

Thanks
