In his guide "How to create your customized Bitcoin-Address (vanitygen) step by step" 1miau already explained how to create a "Custom" Bitcoin address using vanitygen.
Examples (BTC):
However generating such a custom address does not only work for Bitcoin, but also for Ethereum.
Bitcoin addresses are Base58 encoded and can contain the following characters:
When creating our Ethereum address, we unfortunately have to limit ourselves to the hexadecimal system with the following characters:
A few examples of custom ETH-addresses:
0xcafebabeb69f2361cec1106cb26e3f422b65442f
0xdeadbeef36072d66d93b2c9fda370c06964262b2
0xbadc0dedf5b784a70bc9a8c8476b5c88e9f6f49e
0x11111111262b236c9ac9a9a8c8e4276b5cf6b2c9
Example of "Hexspeak":

For creating our desired address, we'll need some computing power and the time it takes to score a hit increases with the length of our prefix.
Available Tools:
VanityEth
- only uses CPU (-> slow)
- Open Source
- trustworthy source
https://github.com/MyEtherWallet/VanityEth
profanity
- uses GPU (-> much faster)
- Windows/Linux
- Open Source
https://github.com/johguse/profanity
vanity-eth.tk (online, therefore not recommended) [1]
- only uses CPU (-> slow)
- browser-based
- Open Source
https://github.com/bokub/vanity-eth
In this guide I will focus on creating a custom ETH-address utilizing our CPU using "VanityEth" - if you've got a GPU you might also want to check out my [Guide] on how to create an Ethereum custom-adress utilizing your GPU

Prerequisites:
- Node.js
https://nodejs.org/en/download/
Windows Installer (.msi) [32- or 64bit depending on your OS]
_______________________________________________________________________________ _______________________________________________________
First we need the current source code of VanityEth, which can be found at the following link:
https://github.com/MyEtherWallet/VanityEth
Navigate to "Clone or download" and click "Download ZIP".
Extract the content of the "VanityEth-master.zip" to your C:\ partition..
Now we start a command prompt by entering "CMD" in the Windows search or open the run dialog box by pressing the [WINDOWS] + [R] key at the same time and start the command prompt by entering "CMD".
Run the following commands to switch to the folder containing the contents of our previously extracted .zip-file followed and installing the VanityEth-Package using npm.
We're ready to start generating our address (I'd recommend disconnecting your internet connection first).
Assuming we'd like to have an address starting with the prefix "0xDEAD" (e.g. 0xDEADxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx), we'll have to use the following command:
As soon as a matching address has been found, it will be saved to a text-file with the corresponding private-key.
You can find the text-file in the VanityEth-master folder on your C:\-drive ( C:\VanityEth-master\"VanityEth-log-[...].txt) [2][3].
Syntax:
If you have any questions please feel free to ask anytime.
