Understanding Networks

Traceroute

The only frequently visited site from my browser is my personal website and I'm either at 370 Jay st. or at home. I rarely use my smartphone's browser, but since I recently switched to Google Fi as my phone carrier from T-Mobile, supposedly Google Fi switch between networks and connect the user with the strongest available at any given location, it would be interesting to find out which carrier I am actually connected to.

1. Trace from NYU

The trace started from my local address to an NYU location. On line 4 the trace hit a a fire wall: Next-Generation Firewall - (NGFW) by Palo Alto Networks. Connections bounce between NYU networks until line 9. Line 12 show that the ISP for this connection is NYSERNet. Tracing is blocked after line 15.

2. Trace from home

I use Verizon Fios as my ISP at home. The service is pre-installed in the building and when I signed up, I simply plugged in the wire. Up to line 6, all the traces appear to be on gateways.

3. Trace from smartphone hotspot

The warning of multiple addresses reappeared when tracing from my smartphone hotspot. It was again traced to proxy-ssl.webflow.com. It was first redirected (Line1) to an address in Los Angeles, and ended up at T-Mobile USA, Inc. in Bellevue, WA (line9).

Both times, where I was redirected to proxy-ssl.webflow.com, the gateway had consistent IP Address at 96.223.9.102, where registered under Comcast Cable Communications, LLC in Mt Laurel, NJ. So want is Proxy SSL?

Proxy SSL

A proxy is used to mask your IP address, when you make a request. SSL stands of Secure Sockets Layer, will encrypt the data in transfer. A regular HTTP proxy may be anonymous, a HTTPS proxy(same as SSL Proxy) also hide the encrypt the data packets.
