What hardware do ISPs use?
The workhorse of the industry, the Cisco Catalyst 6000 Series Switches , have long served in data centers as the primary high end piece of LAN hardware. In many cases, ISPs have pressed them into service for the Internet as well, with some very careful management to account for the lack of buffering within the switch.
How does ISP work?

The servers provide these files through their ISP. Examples of ISPs include AT&T, Comcast, Verizon, Cox, and NetZero.

Some Internet Service Providers (ISP) require VLAN tagging in order for their modems to communicate with wireless routers. To confirm if your ISP uses VLAN tagging, or if you have IPTV or VoIP service through your ISP, check with your ISP.
Why do ISP use VLAN?
A virtual LAN (VLAN) is a local area network that categorizes client devices and workstations despite their geographic location. VLAN tagging is performed by some ISPs to recognize a network and ensures the network receives the right information.
How does ISP assign IP address?
Most ISPs run DHCP servers and dynamically assign their customers IP addresses just like your router does on the home network. This makes sense because as customers unsubscribe from internet service, the ISP wants to get that IP address back to assign to a new customer!.
Is ISP a server?
An Internet Service Provider (ISP) is the industry term for the company that is able to provide you with access to the Internet, typically from a computer. The ISP is the link or conduit between your computer and all the other “servers” on the Internet.

Regardless of what physical connection you have from your ISP: coax cable, fiber optic, phone line (DSL); they all lead back to a network switch at the ISP.
How do ISPs route traffic?

What is a VLAN switch?
A VLAN is a set of end stations and the switch ports that connect them. Like a bridge, a VLAN switch forwards traffic based on the Layer 2 header, which is fast. Like a router, it partitions the network into logical segments, which provides better administration, security, and management of multicast traffic.
What is VLAN tagging in networking?
VLAN tagging is a method through which more than one VLAN is handled on a port. VLAN tagging is used to tell which packet belongs to which VLAN on the other side. Independent logical systems can be formed accurately with the help of the VLAN tagging inside a physical network itself.
What is double NAT type?
Double NAT is the name of a scenario in which, simply put, the router is not directly connected to the internet but to another router. Consequently, your router is not receiving a public IP address. This causes problems because your router is not directly visible to our gaming services on the internet.
