From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Lots of good advice here. I'll add that you could develop an understanding of IP networking and how it works on Linux, network interfaces, with containers, with iptables as well as stateful and stateless firewalls, CIDRs and basic routing, IP protocols and some common protocols like DNS and HTTP. This used to be pretty common knowledge in applicants 15 years ago, but very few have it today I find. DHCP and PXE boot is fun to learn too, and is still common in datacenters.
What is the alternative to DHCP? Besides static IPS of course.
Not much, although it's not strictly necessary for IPv6. But not much is pure IPv6 yet. Perhaps 2025 is the year of IPv6!
Oh damn you're right ipv6 has something included. Ipv6 is so cool, sad that hardly anyone supports it. Not even I myself on my home server because I couldn't get routing from ipv6 to my internal ipv4 hosts working.
