IMPORTANT: This article is primarily for those who manage a protected network, whether it is at a district, at a business, or in a home.

McGraw Hill has a wide range of online products for pre-kindergarten through 12th grade curriculum and beyond.  We use a variety of sites to support the many different services we offer.  To ensure your users will have full access and top performance, please whitelist or prioritize traffic to and from our primary domains (recommended) or specific subdomains below.

Primary Domains, with Ports and Protocols

*.mheducation.com

*.mcgraw-hill.com

*.mhedu.com

Ports: Port 443 (https) is required for most features.  Port 80 (http) is supported for some pre-login pages, like Minimum Requirements.

Domains for Service Partners

Third-party services to ensure performance and reliability.

Administrative Subdomains

Only required by certain administrators and teachers, not students.

Why don't we provide IP addresses?

IP addresses are often tied to physical locations and hardware, which can be more susceptible to temporary loss of connection.  In contrast, subdomains are relatively static and maintain availability and performance of the service, even when some of the hardware supporting it is inaccessible.

If your filters require static IP addresses, you may use public DNS services to look up valid IP addresses for each of our subdomains, and should re-validate periodically to maintain access for your users.  Historically, most of our subdomains keep the same IP address for at least several months at a time.  However, the subdomain catalog.mcgraw-hill.com (and by extension, s3.amazonaws.com) is used to deliver high-performance, high-availability media, and our provider, Amazon Web Services, changes IP addresses throughout the day to accommodate geographic and volumetric changes among active users.
