***********************************
In this video, you’ll see how an attacker might launch a DHCP attack against your network, and you’ll learn how to defend yourself. For example, an attacker might flood your DHCP server with thousands of DHCP Discover messages, which can very quickly deplete your DHCP server’s pool of IP addresses.
You’ll see how an attacker might launch such an attack using a utility called Yersinia, and then you’ll see how to configure Port Security to prevent such an attack.
However, that still doesn’t prevent an attacker from adding a rogue DHCP server to the network and possibly handing out incorrect IP address information to clients. So, we’ll then dive into the configuration of DHCP Snooping, which can block DHCP Offer messages from any untrusted DHCP server.
These topics are covered both on the Certified Ethical Hacker (CEHv11) exam blueprint, and they’re also helpful in your Cisco CCNA and CCNP Enterprise studies.
Enjoy the training!

DORA DORA DHCP EXPLORER 🤟 – I giggled so much at this and I will now DEF remember lol
your title could maybe be dhcp attacks and defence strategies
IF YOU HAVE A CISCO ROUTER *"#¤%#"#¤
What should we do about wireless devices and wireless access point? which assign ip to multiple devices.
Thank you, Kevin, for another classic video.
Love your vid format
DHCP snooping
Rouge DHCP server 7:30
God bless you
Thank You !
Very good video.
What if the DHCP server is a virtual machine on ESXi and not connected directly to the switch, can we still use DHCP snooping? shall we configure it on the trunk port?
Thank you Kevin. I really enjoy watching your videos and learning new stuff. Thanks a looooooooot
Thank
you
Kevin.
Kevin, you’re invaluable. Thank you!
Great job. You are so fluent and professional with the terms. By far the best on YouTube.
The ceh course is gona be packed
Thank you Kevin…another great recap as usual, looking forward to the DAI video
Thanks for another great learning video Kevin!
Great video…thank you Mr Wallace. One other thing I noticed was Switch actually can show you ip addresses attached to specific ports by using dhcp snooping. This is great.
Thanks for sharing
