I was curious to know how much IPv4 address space Facebook actually has. I assumed that they run a large server cluster on their own, but you can’t be too sure.
So I ran a whois on Facebook’s frontend IPv4 address for www.facebook.com:
OrgName: Thefacebook.com
OrgID: THEFA-3
Address: 156 University Ave, 3rd floor
City: Palo Alto
StateProv: CA
PostalCode: 94301
Country: US

CIDR: 69.63.176.0/20
NetName: TFBNET2
NetHandle: NET-69-63-176-0-1
Parent: NET-69-0-0-0-0
NetType: Direct Assignment
NameServer: DNS1.SCTM.TFBNW.NET
NameServer: DNS2.SCTM.TFBNW.NET
NameServer: DNS04.SF2P.TFBNW.NET
NameServer: DNS05.SF2P.TFBNW.NET

I then ran a scan of their entire IPv4 address block, 4096 IPv4 address in total, and only 421 are used. Even if you subtract 16 IPv4 address for the necessary broadcast addresses, then that’s still a pretty low usage percentage (421/4080 is about 10%).
I guess I really shouldn’t be surprised, most companies are like this. They grab up quite a few blocks and then blame other people for the lack of IPv4 addresses. Although IANA did reserve quite a few addresses for internal networks (about 18 million) and multicast addresses (about 16 million which don’t even route properly most of the time). That still leaves 4, 260, 967, 296 addresses though (2^32 - 34 million). Enough for much of the developed world. Well whatever happens, I just hope the transition over to IPv6 makes public Internet Protocol addresses available to more people in the digital industries. Heck 2^128 addresses is more than enough for everyone to have quite a few of their own IPv6 addresses. The only problem with that though is the routability issues caused by dividing up the public Internet into so many pieces.
The interesting thing that I found out from running a scan of Facebook’s IPv4 block is that they created a group debt tracker application called MoochSpot.

| Hello Jason-
At this time we do not currently support IMAP or POP for the student web mail. The only option I can offer is to have your student e-mail forward to a different account (i suggest google since they do allow IMAP and POP configuration), and then retrieve it that way.
If there are any other questions, please contact us again!
Thanks!

Is there a way to access my century email account via imap4 or pop3? It would make things more convenient than always having to use the Outlook Web Access interface.
Thanks for your time, Jason Zerbe |
Simply shocking! This is a college mind you.

Today I finished up a major contract coding job today for this clothing company called Hullabaloo Apparel. They create very unique designs and then print them on various clothing items. Their idea of clothing is not for quick laughs or in-crowd designs (like most online clothing shops), but universally sweet designs. From the various things I’ve heard from Erik and Yuriah (the co-founders), they have already been doing quite well, and needed a web-presence to expand their market and for explaining their brand. Which is where I came in.
About two and a half weeks ago, after showing Yuriah a few tricks with his Mac, he asked me if I would be up for doing the website for Hullabaloo Apparel. They needed a website up asap. So I cracked out various designs from what Yuri described to me and settled on the fourth design in a series of high-contrast xhtml/css designs I put together.
So I jammed away this past week, after getting approval, and am now done.
A couple of things I wanted to write down:
- PayPal has an integrated shopping cart that can take in many different variables (such as sizes)
- PayPal has integrated shipping calculators (for various locales) when a user checks out
- Instant Payment Notification works best for subscriptions and individual (digital service) items; it looks best to have the IPN script running on a SSL host
- It is possible to give site owners access to Google Analytics on the fly, by setting up a Google account with an email of your choice; and then use said account via an auto-login script
- Submitting a form via a JavaScript link is done like so (where “monkey” is the name of the form. <form name=”monkey”></form>:
<a href="javascript:document.monkey.submit();">Submit Form "Monkey"</a>
