For email system administrators: whitelisting DonorsChoose.org IP addresses

Many teachers need to receive critical messages from DonorsChoose.org using a school district email address. If teachers in your district report trouble receiving these emails, you can whitelist these IP addresses:

  • 50.31.41.150 (name = o1.sg.donorschoose.org)
  • 74.86.203.60 (name = ext2.donorschoose.org)
  • IP address range: 64.34.60.24-64.34.60.31
  • IP address range: 64.34.80.160-64.34.80.191
