Traced Routes

The websites I visit most frequently are a little boring. According to what Chrome, my browser, suggests, my number one visited website is Twitter, followed by the (in?)famous data journalism blog FiveThirtyEight, then ScaryGoRound.com which is a webcomic I’ve been reading for almost 15 years, then Gmail (the Inbox flavor), then Github, and then my own blog which you are reading now. I think that last one is only because of how often I need to double check that my posts have actually made it online, not because of the love I have for my own posts. For the most part I use the internet from my home network and NYU’s network. I also make use of my cell network but I don’t know how to check those data.

So I divided up my investigation into six websites from two locations. I used traceroute, whois, my browser, a GeoIP Lookup Tool, nslookup, host, and nmap just in case someone left a port open :)

Two examples of routes:

The At Home Analysis

All my routes from home had the same exact five first lines, with the first being my router. Poking around the next four (well three really since 2 is always a mystery bounce) I found that, unsurprisingly they all belong to Time Warner, my ISP, and they all had nearly identical WhoIs entries.

Time Warner I know about because they send me a bill each month, but what is Road Runner New York (RRNY)? Apparently it is Time Warner’s attempt to brand their high speed internet service as a commodity, dating back to 1998. And apparently I must have Road Runner® Turbo with PowerBoost®, but it’s a shame that even as a reliable customer I’m no longer able to access the fastest Road Runner® customer portal ever. Now I said nearly identical WhoIs entries, the only difference between them being that the last IP address carried a slightly differing comment:

Comment:        Allocations for this OrgID serve Road Runner residential customers out of the Columbus, OH, Herndon, VA and Raleigh, NC RDCs.

So it seems that, oddly enough, either Time Warner has started to misallocate their region-defined IP addresses or my traffic was heading down South. Further investigation, as you will see, shows that the first is true.

However before getting into the IPs further down the line I thought that maybe those ARIN links would be interesting but they were all just JSON files and who has time to parse JSON in 2018. Well apparently I do or I love procrastinatory yak-shaving because I looked through them.

Some interesting bits: * Time Warner has something of a formalized process for law enforcement tracking IP ownership, but it’s linked to under the Charter/Spectrum brand part of their web presence, a cautionary tale to the dangerous obfuscatory pitfalls of corporate mergers:

{
"title": "Registration Comments",
"description": [
"IP Addressing is used for corporate IP allocation and administration, we are unable to provide or reply to inquires regarding specific IP address lookups or subscriber information. ",
"",
"Law Enforcement Officials please visit:  http://www.charter.com/lea  for assistance on subpoena, identification, and escalations. This information is for Law Enforcement officials only."
]
}
  • Road Runner owns big blocks of IPs, which are “NON-PORTABLE”, which probably has a specific meaning.

    "handle": "NET-24-194-0-0-1",
    "startAddress": "24.194.0.0",
    "endAddress": "24.195.255.255",
    "ipVersion": "v4",
    "name": "ROADRUNNER-NYS-4BLK",
    "parentHandle": "NET-24-0-0-0-0",
    "remarks": [
    {
    "title": "Registration Comments",
    "description": [
    "ADDRESSES WITHIN THIS BLOCK ARE NON-PORTABLE"
    ]
    }
    ]
    
  • Road Runner’s Registration IP is the deeply sinister 66.66.0.0, which I can only assume given the packet loss in trying to ping it is buried in the depths of hell.

👻 🌵 ✨ $ ping -c 3 66.66.0.0
PING 66.66.0.0 (66.66.0.0): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1

--- 66.66.0.0 ping statistics ---
3 packets transmitted, 0 packets received, 100.0% packet loss

Back to the New York or Virginia issue, the subsequent IP always seemed to be close enough to New York it didn’t seem like it was going down to Virginia/NC right away. How they all shake out:

  • My blog website’s trace record goes dark at this point, giving only empty bounces after the final Road Runner trace

  • FiveThirtyEight switches to Comcast’s servers in Newark before going dark

  • Github goes to Level3 in Newark and then to Level3 in Washington DC and then goes dark

  • ScaryGoRound ends up at the seemingly hegemonic Tata Communications’s routers in Newark for seven or so hops before ending up well… here

    13  cyclone.yadda.net (50.116.60.26)  3.889 ms  4.771 ms  4.089 ms
    

    at Linode’s servers on 329 E. Jimmie Leeds Road Suite A, Galloway NJ. To get that address I used the delightful Data Center Map. But what is cyclone.yadda.net? It exists as a web page but the content there defies both my capacity and my will to understand. Maybe Don Sutherland owns Linode?

  • Gmail makes one hop to Tata here in NYC but then hops onto Google’s IPs for three hops and never leaving NYC, I assume going to either their office here or some data center they were able to buy on the High Line or something, I don’t know what they are capable of doing. Thus far we’ve only made it to Washington D.C. but…

  • Twitter seems to go all the way to the top. Which is to say, to California. After two subsequent hops in the Time Warner family of routers it made a hop to Twitter’s server in Raleigh Virginia and a * * * it looks like it goes directly to the bay area. I’m a little suspicious of the geoIP tools but I couldn’t turn over anything to disagree with that. The Twitter WhoIs page was also a little interesting.

Instead of the perfunctory “IP abuse” faceless corporate email addresses (I’m looking at you network-abuse@google.com), Twitter includes the emails and phone numbers of two real live human beings.

I became curious about these two Twitter employees, and I wanted to know why they had been added to the WhoIs record instead of leaving it with just the corporate accounts. What would happen if they quit? Would Twitter have to immediately update its record? Obviously the reasonable thing to do would be to call them but I chose instead to search for them online, but I began to feel a little weird and stopped once I found their LinkedIn profiles, birthdays, zip codes, and dating profiles.

The At School Analysis

The biggest difference between at home and at school is the NYU network, which for the most part would make similar handoffs to Level3 or Comcast that Time Warner was making. All that I found particularly interesting about NYU’s routers was that it received its IPs via ‘Direct Assignment’, and that it had been registered all the way back in 1984!

There was only one other point of difference, one that I have no explanation for. In going to FiveThirtyEight from the NYU network, instead of heading to Comcast and bouncing around forever, it goes to 60 Hudson, then leaves the domain of ARIN and hops RIPE, first to Tiscali International’s German servers and then to TeliaNet in Sweden. Why a blog written in New York is sending me to Sweden is A MYSTERY.

End Note: I did try to nmap things but never found any open ports. Guess the net’s wild wild west days are over. Maybe it’s time for this old console cowboy to hang up his hat.
