We are switching from at&amp;t to Comcast ISP. &nbsp;When we switch what to I need to keep in mind? &nbsp;What pitfalls should I be aware of?. &nbsp;<br />
<br />
The basics<br />
We host our own website<br />
Our domains are registered though a separate service (not through our ISP)<br />
All traffic comes in to a router then a Firewall then to our network<br />
Email filtering is hosted by a separate service, we use exchange 2010 once we receive it<br />

Thank you in advance<br />

Switching ISP to Comcast

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
