There will be a network! Available in both wired and wireless flavours Be sure to read the Survival Guide before connecting your devices.

(more to come)

Rules of Conduct

  • Be fair! Do not do to others what you do not wish done to yourself!
  • Protect your computer! We cannot be held responsible for any damage your computer may face due to attachment to our network. Be reminded that both internet access and the local network are unfirewalled and unfiltered. Even well-maintained systems can be attacked and get hacked, even more so at a hacker event.
  • Do not run your own DHCP server! Doing so is harmful. We will detect, locate and disconnect you.
  • Do not send IPv6 Router Advertisements! Again, we will detect, locate and disconnect you.
  • Do not ARP spoof or otherwise impede the operation of the network! We are quite able to find and disconnect you, if necessary.
  • Think twice before you do something that affects others! If you hack someone, you might be prosecuted. Be aware that we cannot prevent law enforcement from acting within or related to our network.


We can't live without wireless access anymore, so we've built an awesome wireless network again. The setup is improved from last year, please read the following carefully.


The following SSIDs are provided:

  • 30c3 (802.1X (see below), 5Ghz)
  • 30c3-legacy (802.1X (see below), 2.4Ghz)
  • 30c3-open (open, 5Ghz)
  • 30c3-open-legacy (open, 2.4Ghz)
  • spacenet (federated hacker authentication system, see

802.11x, encryption

Due to popular demand (and with security in mind) we provide 802.1x. This allows you to setup an encrypted connection and prevent attackers to capture unencrypted data from the air. Keep in mind that this won't protect you from all other network attacks and you should still be aware that you are at a hacker conference!

You might think now: "WTF!? Do I need to register a user and password blah, blah". Fortunately not. You can use any username/password combination to login (example: "user: fbhfbhiaf pass: bgufwbnkqo" is valid), because we don't care who logs in and who you are. We just want to encrypt your data.

Nat64 & Static-IP

Just like last year we'll still be providing Nat64 and Static-IP. We're however using 802.1x for this instead of separate SSIDs. If you use the username/password combination nat64/nat64 you'll be pushed into the Nat64 vlan. If you use fixip/fixip you'll be pushed into the fixed-ip vlan (get you're static ip at the helpdesk).

2.4Ghz & 5Ghz

In the previous year we've tried to use the vendor implemented workarounds like band-steering and band-select to let clients use 5Ghz. This might work in a controlled enterprise environment, but it doesn't work with 5000 hackers with 50 different operating systems.

The default SSIDs are 5Ghz only. The "legacy" SSIDs are 2.4Ghz only. If your client supports both, don't use the legacy SSIDs. If you only see the legacy SSIDs, consider upgrading your device. We cannot guarantee that 2.4Ghz works.


To keep the wireless working for you, keep a few things in mind:

  • We're aware you can break the Wifi infrastructure. We're hoping that you won't and don't want to be chased by 5000 hackers through Hamburg.
  • If you want to download terabytes of data, you might be better off connecting to the wired network
  • Don't set up any of your own access points. Wireless experimentation is only allowed in the hackcenter, 2.4Ghz at channel1 and 5Ghz at channel 36 (20Mhz!). When we find you, the AP is ours!


If you have questions about the network or need help connecting or want to drop off a server for collocation during the event, drop by the friendly people of the NOC Helpdesk, located near the Infodesk in the Main Foyer.


The world supply of IPv4 addresses is nearing depletion. To get used to the future and gain some experience with how it may soon feel, ports 1-4 on each switch function as "DNS64", one of many transition strategies from IPv4 to IPv6. Your operating system will need to support native IPv6 and DHCPv6, or configure this IPv6 address as nameserver: 2001:67c:20a1:2251::53

The same goes for the 30c3-dns64 SSID.

Please report your experiences with this in the Talk page.


This is a list of companies providing network hardware and connectivity services. The event would not have been possible without their support (and a few unlisted), and we thank them for it.
