Traffic Server Address?

bobnuts1 · Posted: Sun May 30, 2004 4:13 pm Post subject: Traffic Server Address?

Does anybody know the internet or IP address of the server that is by TTN3 to obtain the traffic information?

I have the same connection problems (discussed elswhere) of using O2 and a Nokia 6310i and would like to try an experiment that avoids the use of the O2 DNS server by placing an entry into the "hosts" file on my PDA.

TIA

Richard

As Traffic uses ITIS for its data, I looked at ITIS free traffic map and noted the ip address to be 62.225.145.21. A trace route took 12 hops then timed out, (probably due to icmp packets being dropped). each hop was about 15-30 m/s, (The ip address is based in Germany)

I know its a very (Make that very very) long shot that they use the same address for this, but only one way to find out, & please let us know

Cheers

Well, I think I can help. I updated TomTom traffic over my WLAN whilst monitoring the firewall logs from my router, watching for a DNS lookup for something 'TomTomish' ;) And there it is

I have tried using the hosts setting in the TCP parameters but it makes no difference.

HKLM\Comm\Tcpip\Hosts

I assume that this key used in PPC2002 can also be used in PPC2003.

Well, it seem to have improved things here.

I have just ran a 1 hour test and did not get any connection errors. In fact the whole connect and update process seems a lot faster than before but maybe the server loading is not so high today as its a public holiday.

Also ran a 1 hour test using my wireless network (via another isp) and that did not fail either - both would have failed to connect at some point.

I modified the "hosts" on my very old HP Journada with the use of Marc Zimmermann's Pocket Hosts app that can be viewed here > http://www.zimac.de/cestuff.htm

Hope this helps

I'm pretty sure there's issues to do with the use of the Hosts feature in Pocket PC 2003 (or at least with the use of Pocket Hosts) - but I can't remember what they are - sorry. Maybe Google Groups on the microsoft.public.pocketpc newsgroups will dig up something.

I have confirmed that the DNS hosts setting does work in the registry in PPC2003 and that the URL and IP address mentioned above are correct for the operation of TT Traffic.

I have also found that 02 recommends manual DNS settings but automatic appears to work better. Maybe those with 02 should try the automatic.

If I repeatedly update traffic information, 02 frequently does not download it all. You can watch an incident appear and dissapear with each download. Orange usually but not always downloads then all. Connection through my router to the internet, appears to always download it all.

I have found that the handset (Nokia 6310i vs Ericsson T610) makes no noticable difference once correctly configured.

bobnuts1.. thanks for the reply

Which IP did you put in the hosts file, or did you use both?

The idea of placing the actual IP address in the hosts file is an interesting one to play with for a while.. From what I gather from other posts is that performance of traffic varies by network operator so DNS resolution might be a factor. (by placing the host name & IP in the hosts file should bypass the DNS lookup).

I don't know pocket pc OS so well, so if one does a straight test by switching phones, I wonder if the PDA is caching the host lookup, hence no perceived improvement.

Mr T, which IP did you put in the hosts file?

Cheers

Forgot to ask... With the IPs in the hosts file, have you run a comparision with connecting via LAN against GPRS to see if you get an equal download? As this appears to be a commom problem

62.250.16.51 is the IP against the name of www.tt1.nl

Blocking this IP or putting another incorrect IP against the URL in the hosts entry causes Traffic to fail.

Mr T..

Putting IP addresses into the hosts file is not an attempt to block anything, its a way of bypasing the DNS lookup cost to resolve a host address to an IP.

Our test here is to further validate if the issue of why traffic update on lan differs from that of GPRS is due a latency issue with DNS lookup resolution at service provider.

Timc,

I think Mr T's statement is to confirm that 62.250.16.51 is the correct IP address as putting a block on it causes Traffic to fail. Thats how I am reading it anyway.
