I'm trying to reproduce this on a macbook. I'm a developer, not a networks guy so please excuse me for not knowing the basics!

After doing `sudo tcpdump -In -i en0 -s 2048 -A dst i.instagram.com`, and using every instagram feature from my iPhone, nothing happens in the terminal.

```

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on en0, link-type IEEE802_11_RADIO (802.11 plus radiotap header), capture size 2048 bytes

```

I try running with -v and -vv, but no difference (except it doesn't suggest running in verbose more).

After hitting C-c to stop the program, it outputs

```

^C

0 packets captured

29816 packets received by filter

0 packets dropped by kernel

```

So there's a lot of things being captured, but the filter does not catch my Instagram activity. I'm logged in there, refreshing, getting images, getting followers/following, etc.

EDIT: oh shit, HN doenst do markdown. That sucks.
