I was trying to determine why there is  a Internet slow access problem. I used tracert but the second and third entries are not even located on the local network.
  1    <1 ms    <1 ms    <1 ms  192.168.1.1
  2    16 ms    14 ms    13 ms  192.168.33.254
  3    15 ms    13 ms    15 ms  192.168.33.165
  4    17 ms    22 ms    14 ms  ge5-0-4d0.cir1.la3-ca.us.xo.net [216.156.64.45]

 I can ping this addresses but using something like nbtstat -A 192.168.33.254 does not show a computer name.

C:\Documents and Settings\joe.davis>nbtstat -A 192.168.33.165

Local Area Connection 2:
Node IpAddress: [192.168.1.212] Scope Id: []

    Host not found.

C:\Documents and Settings\joe.davis>ping -a 192.168.33.165

Pinging 192.168.33.165 with 32 bytes of data:

Reply from 192.168.33.165: bytes=32 time=14ms TTL=253
Reply from 192.168.33.165: bytes=32 time=15ms TTL=253

Reply from 192.168.33.165: bytes=32 time=15ms TTL=253


What could 192.168.33.254 and 192.168.33.165 be?

Isn't a router or any different internet provider device?

they will probably be routers on your ISP's network.

I'm guessing that 192.168.1.1 is your internet gateway.

who is your ISP?

Is it a business network. if it is there are chances that you have other routers in place.  before you reach the ISP. For me it looks like you have two more routers after your default gateway before it reaches your ISP

I do not understand Andy_23 comment.

 I am expecting a public IP address for any ISP routers. However, maybe the addresses are ISP routers. Yes, 192.168.1.1 is the internet gateway.    ISP is Earthlink.

 Yes, this is a business network. No other routers in place. The  DSL modem is connected to the router with gateway 192.168.1.1.  The router is Ipitomy 1000. Maybe the router has something strange.

Hi connect the dsl modem directly to a workstation and see what tracert gives you now. So we can figure out if the router is the culprit

the additional hops are the routers that take you through the Earthlink network and out to the Internet.

In the UK, a cable operator called Telewest had a similar setup.

By doing it this way, they don't have to allocate you a public IP address as they can NAT a pool that is available.

Here is the request  trace using a laptop through a modem.

Tracing route to carouselschool.com [66.147.244.180]
over a maximum of 30 hops:

  1    15 ms    15 ms    14 ms  192.168.33.254
  2    14 ms    17 ms    14 ms  192.168.33.165

The proves jakethecatuk theory.
