To what? To a machine outside your ISP?

Actually when I look up the host (I am not using netspeed):
$ host www.irun.net.au
www.irun.net.au has address 192.168.0.3
$ host -t ns irun.net.au
irun.net.au name server ns2.netspeed.com.au.
irun.net.au name server ns1.netspeed.com.au.
$ host ns2.netspeed.com.au
ns2.netspeed.com.au has address 220.127.116.11
OK irun is owned by netspeed.
This means it is advertising www.irun.net.au as having that address
which I don't believe is correct.
My memory of netspeed is that they occasionally scramble their DNS.
Give them a support call.
Try going to an IP site like one listed at myip.com.
for instance :
This won't necessarily give you your IP. You need an https site for
that because your ISP may have a transparent proxy and with http you
are only seeing the IP address of the proxy.
This is the only one of those sites that seems to do https
