Does anyone know who Cogent Communications Inc. are?
http://www.cogentco.com

I get spidered by these guys a lot and all I
can tell from visiting their website is that
they are a fiber network or something...

...or maybe they just have some bad spider management going on...

...or maybe they need to spider me daily
and are an information provider for some bigger entity, like AOL,
Altavista, Google, the mafia, the FBI, or
some other big company?

Does anyone know anything about this company?

Thx,

Jim

I think they are a cover company!

Cogent Communications Inc

But that is only my opinion.

By "Cover Company", do you mean a "Front" for something illegal, evil, or otherwise?

Like they are the ISP for the Hells Angels or something???

Thx,

Metacarta uses Cogent, and Metacarta is spooky [nytimes.com].

It looks like Metacarta could be using
66.28.68.234
66.28.68.235
66.28.68.236
66.28.68.237
to map the Web for the NSA or CIA, according to that NYT piece and our logs.

I have seen reports that User_agent ia_archiver (Wayback Machine) was appearing within a couple of small blocks inside Cogent's Class B, but this could be a cover. At any rate, Cogent sure doesn't volunteer much using various tracing tools. We have no patience with any of this stuff, so we blocked the entire Class B.

We've gotten a few visits from these ip adresses in the last 10 days:

66.28.68.236
66.28.68.237

The user agent is: larbin samualt9@bigfoot.com.

jrota, do you have a user agent you can give us for your visits?

How Do You Block an Entire Class B?

User-agent - hmmm... how are you getting an email address from these guys...is that information somewhere in the log, or are you doing a whois on the address and finding it that way?

I'll have to check the log the next time I see one, but it's definitely the 66.28.*.* net address that I remember seeing like 12 times daily...

How do I find out the User-Agent's email address?

Thx,

Jim

I believe that user-agent is worthless.

First of all, larbin is a French off-the-shelf bot something like Wget.

Secondly, bigfoot is now in the philippines. That email address is about as informative as a hotmail email address would be.

Finally, look at the last two hops on this trace:

19 65 ms 70 ms 71 ms metacarta.demarc.cogentco.com
20 70 ms 66 ms 68 ms 66.28.68.237

ia_archiver was seen from 66.28.98.* and 66.28.250.*, the first of which gets easily confused with 66.28.68.*

Not that their data wouldn't be interesting for the spooks... ;)

I've been reading up on Cogent. It's a new company -- only about a year old. They bought up PSINet assets in a bankruptcy sale. Their CEO and directors and officers don't look suspicious at all to me.

They specialize in multi-tenant office buildings, and supplying high bandwidth to the building at bargain-rate prices. Their prices for big bandwidth are so low that everyone is amazed.

Their billing is very simple and streamlined. They probably don't even know much about those who lease their bandwidth.

Many bots might be tempted to lease bandwidth from a company like this. Unfortunately, it's not easy to trace anything through Cogent because the record-keeping seems sparse.

Perhaps we should make a distinction between Cogent and those various crawlers who might be leasing bandwidth from Cogent.

Hence, I tend to think they are
simply a messed-up ISP who is
a bit confused about spider etiquette
and should turn themselves off for awhile
or at least make themselves less frequent
but I bet it's all part of their marketing plan
to get us wondering who they are...

...maybe someone needs to tell them they are creating a disturbance...

...except they are really good at keeping themselves hidden from enquiries, so they seem pretty good at keeping us all in suspense, wondering, nonetheless...

I agree that Cogent shares the blame. Anyone who sells bandwidth in large enough chunks to interest professional spiders, ought to have rules for those spiders.

They ought to insist on accurate user-agents and full traceability and email addresses for reporting abuse.

On Cogent's configuration of various blocks, the tracing should provide the usual amount of information on who is assigned what blocks.

The IP numbers should all reverse-resolve.

Cogent is committing slow suicide by not insisting on this. I think it's an oversight, not a marketing plan. There's nothing more efficient than a secretive spider for generating bad publicity and paranoia.

We'll keep them blocked, thank you.

I agree they should be held accountable. All too often mischievous operations are implemented behind the veil of an ISP. Of course the ISP will claim no knowledge and state that "appropriate action has been taken", when in reality they are working together.
