DNS (noob) questions.

Hey, I recently had plex.tv blocked ( I could access parts of the website but not the specific plex.tv i.e I could access plex.tv/support/FAQ) and twitch.tv where everything loads except the actual streams.

I finally figured out that it had something to do with the DNS. Got some information and decided to switch to google DNS.

Sorry in advance because I am not really that tech savy with how all of this works and I might have used the wrong terminology. Keep that in mind.

My questions are:

Since I live in a complex with lots of apartments where the landlord have his own server setup that we connect to (like if you are at school or work but more private), do you guys think he blocked the websites I mentioned ?

Did my isp block twitch.tv / plex.tv?

Should I be careful wth google DNS? Do they track every move you make on the internet?

How to use SRV properly?

I have a Minecraft server running on a non standard port.

I thought that you could use a SRV record to forward traffic to a port.

Example: xxx.anesthesia.rocks (Default port 25565 if left blank) would forward to 142.4.212.51 port 9090 or yyy.anesthesia.rocks port 9090.

However, I can’t seem to get this configured properly.

Here is a screenshot of the setups I’ve tried: http://imgur.com/wJRuo1s

Anyone have any ideas or help they could suggest?

DNS Granular Access

Does a provider exist that allows me to grant someone access to manage only one domain out of the several on my account? I am an IT admin and we’ve recently added a new division that deals with managed services. They need to manage a specific domain. I would like to keep this domain under the general corporate umbrella and grant them the access they need. I’ve looked into Go Daddy which appeared to offer this capability but it looks like they are phasing it out… Thanks.

2008 R2 – Fixed DNS to DNS query ports?

Is there a registry setting to set a fixed port for DNS to DNS query and responses? We’re in a pretty sure environment and ports being randomly chosen between 49152-65535 makes it a bit difficult to lock things down.

DNS 53 works fine. This is for DNS to DNS requests. Like kicking off DNS Manager and connecting to a DNS server to manage it. Unless we open the full range from 49152-65535 connectivity fails.

We were able to accomplish the same kind of fix for RPC traffic: https://support.microsoft.com/en-us/kb/224196
