So, has anyone else noticed that we now have a new iBurst Blackhole Gateway?

I guess this means that 196.30.31.100 was "retired"...

How long have you been connected for now?

DaveBuchanan1337 · Feb 21, 2005

you are smarter than most, ic. certainly smarter than me. will reconnect after I trade some stocks ;-)

ic · Feb 21, 2005

Thanks, but I know I'm not that smart ;-)

Anyways, here is a tracert I did after having had [more than the usual] problems [this evening] with my previous [to this] connection via 196.30.31.100:

hokay - here is my updated ifconfig -

ppp0 Link encapoint-to-Point Protocol

still the same gateway - I would think the difference comes from using alternate towers, but I heard that absolutely no ip work is done at the base station - perhaps they are testing the new gateway on a specific test subnet?

ic · Feb 21, 2005

Very odd, I had been wondering if they were still going to be doing this "New Port Shaping" today, perhaps this is yet another experiment, and despite our UT's both being connected to the same base-station (or so we both presume)...

Can you confirm that 196.30.31.100 is still your 1st hop on a tracert?

Looks like it's back to 196.30.31.100. I did catch them in the act of doing something though, I wonder what they were up to...

I remember you mentioned it, but I think that's an example of fluke, bcos I don't have that problem on the 1st hop, unless it's bcos your connection is always so fast & mine is always incredibly slooooow...

WickedWeasel · Feb 21, 2005

it could be that they are using a new set of ip's allocated and ARIN have not resigned them

On the Cape Town CBD site we have always gone go through two private range ip gateways.

If no IP work is done at the base station then why waste allocated IP's? It appears it is irrelevant what IP is assigned.

ic · Feb 21, 2005

Hmmm, very interesting, might not necessarily be the base-station(s) as such, but perhaps these are the "Core Network" and/or "Peering Links".

I think we need more tracert listings, along with base-stations that are within range.

They definitely have some routing ability at their first hop.

Iburst has its own route so we can authenticate here in Cape Town.

ic must be one of those special case scenarios

WBS: "ahh bugger him, just send him to that blackhole we've secretly been working on, maybe throw in a couple hax and viruses"

TheRoDent · Feb 22, 2005

Oh my ***. 172.* is a reserved IANA address. In other words private. They're obviously trying to do _SOMETHING_ but it's clearly a frigging stupid idea.

Welcome to WBS's capping/traffic management attempts.

alchamy · Feb 22, 2005

I cannot pick this address up running a tracert, however I did notice this address popping up the weekend the auth server failed. Since then I could not duplicate the result. I managed to pick it up using the advanced tracert in Tweakmaster.

also got 172.16.0.101 after a disconnect just now. That brings to mind that disconnections are not always because of bad connections but WBS screwing around with the systems
