![]() ![]() NOTE: this approach does not take into account administrative or domain boundaries, and is meant to show that "minified" SPF records are possible. If you do not have a complete understanding of what this means, do not use this. By flattening a record, you will not receive changes that come from "include" unless you track them yourself and manually update the record. This approach is considered experimental and should not be used without careful monitoring. Each SPF record is kept to less than 512 bytes to fit into a single UDP packet (assuming no other TXT records are sharing the DNS label). The dmarcian SPF Record Flattener rewrites this record by removing duplicate netblocks, collapsing any overlapping netblocks, and using 0 DNS-querying mechanisms / modifiers. Duplicates usually indicate inefficient records or redundant "include" mechanisms, and should be removed. The following netblocks have been authorized more than once. Learn more about SPF mechanisms / modifiers.Īuthorized netblocks produce SPF "pass" results (as opposed to "neutral", "fail", or "softfail"). There are no efficiency gains to be made in terms of reducing the number of DNS queries. This record utilizes no DNS-querying mechanisms / modifiers. ![]() Call or email the Office of Student Registration Services at (630) 942-2377 or to receive assistance in registering for classes.
