What exactly are you trying to do?  It looks like it might find {bol}{one-or-more-alphanum}.{one-or-more-alphanum}.{domain}{eol}.  Is that what you want?

keithh at hera:~> cat phred
abc123.hithere.com
abc^123.hithere.com
hitbox.org
www.hitbox.org

keithh at hera:~> egrep "^[a-zA-Z0-9-]+\.[a-zA-Z0-9-]+\.(com|org|net)$" phred
abc123.hithere.com
www.hitbox.org

It works for me.

keithh at hera:~> egrep --version
egrep (GNU grep) 2.4.2
