A Records in DNS - What are...

Generally an A Record is created for @ that points to your web server. Then in C Names you point WWW to @ using @ as a variable. You can point WWW directly to an IP address in an A Record but it is not a "best practice". The @ allows you to point multiple CNames to the main server, and then only change the IP address of the main server when needed. So in CNames you would point WWW to @, FTP to @, and VPN to @ if those services all reside on the main server.

God bless you Eli! Simple explanations!

DNS A-Record: Points subdomain name to an IP Address
DNS C-Record: Points subdomain name to a domain name

OMG - I've been looking someone to give me a simple (and correct) explanation to the A, @, WWW & Cname answer for so long. Thank you.

Hi Eli, what happens when you have just a tenant with MS O365 and no servers, domain controllers - just microsoft platform, ...how do you add dns records?

[offensivebias]

very informative, now im back on track thank you !

[SkippyDoo]

Thank you! This is VERY well explained.
Does the mail record in the A record need to match the servers set up in the MX record? I set up Gmail for my mail server in the MX records, but my host for my website is Bluehost. Currently my website loads, but I cannot receive mail through Gmail (I can send mail though). Should I leave the mail record in the A record or change it?

Eli I love your videos but the audio is really quiet in this series for some reason, any chance you could bump up the volume on the output by say 20%?

Thanks for helping me land my job :)

Thank you! This video was just what I needed!

I'm just learning this stuff at the moment. If you have a domain name and you set an A record to 192.168.1.163 I understand that it's pointing at my vm on the server that is running the website, so it's telling it to go to a device on my internal network. I own the server so it's being hosted from my house, how do I setup DNS to know what my internet IP address is so it knows where my servers are even located?

I.E.
192.168.1.163 is inside my network at home, it's not a public IP, it goes to a vm ubuntu machine running a website
70.147.124.129 is a Dynamic IP (They go more than a year before they cycle it) assigned to me by my ISP

Don't you need to set something up that lets DNS know that the domain is associated to 70.147.124.129 because 192.168.1.163 is on an internal network?

What happened? I'm so glad he's doing teaching stuff again. Is this some kind of experiment of his?

Eli I love your videos! What are your plans for hitting your Million Subs?

Didn’t know Tyson fury became an it geek!! Nice

[raamece]

Hello Eli could you pls make video abt power shell remote scripting 😑

[iftekmahmud]

What the heck? Are you even aiming at beginners bro?

[jonasjensen]

Must say, i normally loves your videos - but this one is way to confussing. Sorry to say!

[DannyVardy]

You're talking tech speak like you're talking to other techies who understand the language. If you're going to make beginner explainer videos, make them for people who are beginners who want to learn the concepts, not like you're sitting around the office lunchroom table discussing things you already all understand, . You've missed the point of teaching...
