poor ping and an illegal IP address

[Graham Vincent]

Hello.

Major complaint today from my son who tells me his ping is so bad he
can't play a decent game of UT2004.

Tracing route to tribes2.games.xtra.co.nz [203.96.92.75]

Trace complete.

Hop 4 looks interesting - Isn't that an illegal address for use in the
wicked outside world? And the 200ms delay from hop 4 to 5 certainly
looks like the cause of most of the lag to the game server.

Any ideas?

Thanks,

Graham

There is nothing wrong with 192.168.253.225 being in the trace.

The Latency between hops 4 and 5 is a "problem" yes which you should contact
your ISP and get them to contact Telecom for them to fix.

Thanks
Craig

To clarify, for the sake of the archives - as this question seems to get
raised all the time.

You can't 'advertise' (make available to other internet users) 192.168.x.x
space (or any other addresses within the spaces defined by RFC1918 - 10/8,
a segment of the 172.16/16 and the 192.168/16 networks.

Thats not to say you cant use them to connect two hosts.
As long as its dealt with *locally* it can be used all you like.
Which is why if you have a Router which uses 192.168 internally, you can
traceroute from behind it over multiple RFC1918 addresses before
traversing to the Internet and the route is fine.

What it means in the below example is that 210.55.64.32 and 202.50.245.9
obviously both have connectivity to the 192.168.253.225 router/device and
have static routes (not routes advertised via BGP or similar) to get to
eachother.

Multiple hop routes tend to operate 'one hop at a time', so if you think
of it that way, theres a number of circumstances that could have traffic
forwarding through RFC1918 address space.

Mark.

(Comments IMHO, etc)
