Full Explanation
Enterprise and organization IP allow lists restrict which source addresses may access protected resources. When enforcement is enabled, GitHub Apps, webhooks, and other integrations that call from fixed egress IPs can fail unless those addresses are allow-listed or the product's supported app-access options are configured. Allow lists do not open the entire internet, are not limited to email only, and do not delete large repositories. Administrators should inventory automation egress, coordinate with SaaS vendors for stable IPs or private networking patterns, stage enablement in audit mode when available, and maintain an emergency break-glass path for outages caused by overly tight lists.
