oops it should.   I will edit.  Thanks for pointing out my typo.

2 - First external hop on a ip with no RDNS.  As these managed dedicated services the pattern seems they dont want to bother with reverse dns.

The problem with saying that is that Plusnet have been shockingly bad recently at setting up the RDNS for new end points (see http://community.plus.net/forum/index.php/topic,134822.0.html - there's end points that have been live for months which still haven't been properly configured). That why Kitz's definition is the correct one to use:

@roseway

If you are on dedicated then you will see a hop with a private IP eg 172.17.xx

I have never seen them setup a gateway with no RDNS, but only the wrong RDNS.

But yes RDNS isnt the only thing to check, you need to know what latency you usually get and if a new extra hop appears with lower latency then you have probably been moved. It might be multiple extra hops, when I was on BT there was about 4-5 hops visible on the BTw routing.

Interesting:

Slight more info, this is my gateway.

You are currently connected to gateway pcn-ar01.

This is located in Colindale Point of Presence

[kitz]

Colindale PoP is where the EU will have exited the Core and joined the more traditional PN routing.

I mentioned in the first post that now they are using dedicated they have the flexibility for traffic to come off any of the core nodes they like.   I wouldnt like to predict what they will do and if they will eventually arrange more peering at certain nodes.   For the time being it looks like traffic is still going through the telehouse peering...  which is understandable as most large organisations peer from here.    They could in future peer direct with JANET in Manchester or the MetOffice in Birmingham etc to decrease latency for those in the north.  Right now it will be more important to get all the nodes connected and customers migrated over.

[jelv]

Rather than it being Colindale specifically I was more interested in the fact that the gateway checker will now tell you if you are on the new network.

[kitz]

Sorry, think I missed the point that it had come from the gateway checker.

Anyone know a  reason why I would have been moved back to the "old" network?

You've posted two tracerts from the old network - could you tell us what made you think you'd been moved to the new one?

[big360]

Plusnet support had said I had been moved when I called them with speed issues. I also thought that unresolved 195.166.130.210 address meant I was on new network but I've just seen the previous posts about the 172. address for new network so I guess plusnet were telling me porkies..

[ejs]

Plusnet did also say that not everyone would see the different traceroutes.

[jelv]

Just had a thought: when I connect I see these entries in my router log:

Code: [Select]

<38> Jan 29 15:41:03 PPP CHAP Receive challenge from rhost bras-red2.sl (Internet)
<38> Jan 29 15:41:03 PPP CHAP Receive challenge from rhost JUNOS (Internet)
I wonder if those change when you are on the new network?

[ejs]

I don't think those will tell you much, unless people can correlate a change in the one like your "bras-red2.sl" with a switch to the new network. I think the first one, bras-red2.sl, or mine like acc-aln6.tw, is a part of the BTWholesale network before it's gone to Plusnet, and the JUNOS part is just the name of the Plusnet gateway.

I think the acc-aln6.tw in mine is the MSE in the Tunbridge Wells exchange, so it's probably not going to change whatever Plusnet do.

[Chrysalis]

Plusnet did also say that not everyone would see the different traceroutes.

Then the rep who said that is probably wrong, I think they trying to cause confusion.

[jelv]

Junos means a bng I think. If you get one of the ag's it gives you it's actual name.

[niemand]

Yeah JunOS is the operating system the Juniper ERXs that Plusnet call BNGs are using.

The other bit I *think* indicates you landed on BRAS Redback 2 in BTW's Slough PoP. Ericsson acquired Redback Networks a while ago hence the Ericsson page. Don't quote me on that, I know BTW used Redback kit extensively at one point.
