networking

Not sure if this is the right place to ask but when i want to go to a website like beehaw.org, my router queries its DNS server which responds with the IP address. But my router doesn't know where to find that IP so it asks a nearby router if it knows and that router passes that info to another router until they find the path.

If wifi is radio waves and radio waves travel at the speed of light where as down a copper wire data travels at only partial speed of light, why is wifi slower?

Is it simply interference from other signals causing constant retransmissions or what?

Also what is a route? Why can't i just shoot a packet from my router to the public internet and that website's router picks it up. Why does it need router's in the middle?

This is a cool project where anyone can make an RNode that can be used for transmission of digital radio signals. Each RNode contains the information required to create additional RNodes.

Reminder for all to upgrade your Fortis ASAP!

What's the 'freakiest' event or situation you've experienced in production?

Looked down at my ThinkPad dock to plug in a USB device and saw a 10 next to it. USB.org has specs on a 10Gbps serial bus.

Time to trash the network. I'm getting a 10Gbps 24-port USB hub. :D

Do you have a preferred vendor for your network gear?

I'll go first:

• Firewalls: Fortinet, ASA, Palo Alto
• Route/Switch: Cisco, HPE/Aruba
• Wireless: Aruba, Cisco, Meraki
• Auth: NPS, ISE, ClearPass
• Monitoring: SolarWinds, Auvik, PRTG
• Automation: Ansible
• SDWAN: PA Prisma SDWAN, Fortinet, Velocloud

Enterprise network and security is where I spend most of my time and thought there may be others out there who want to commiserate with me.
