bresnan.net SPF record
The record on 5 November 2026 was v=spf1 ip4:24.159.193.32/27 ip4:68.115.71.16/28 ip4:24.196.64.32/27 ip4:24.213.60.64/26 ip4:24.247.15.32/27 ip4:24.247.24.32/27 ip4:209.225.8.0/24 ip4:209.225.29.51/32 ip4:64.210.232.0/24 ip4:216.33.127.0/24 ip4:64.209.227.0/24 ip4:68.114.188.0/22 ip4:47.43.20.0/24 ip4:47.43.16.0/23 ~all.
In plain terms, lists 14 IP ranges directly. The top level uses 0 DNS-querying terms; SPF allows 10 in total including nested includes (RFC 7208 §4.6.4).
It ends in a soft fail (~all): mail from unlisted servers should be accepted but treated as suspicious.
bresnan.net DMARC policy
_dmarc.bresnan.net returned no DMARC record on 5 November 2026. Receivers therefore get no instruction about mail that fails SPF and DKIM, which makes @bresnan.net easier to spoof (RFC 7489).
Can you verify @bresnan.net addresses?
Our checker treats @bresnan.net like any domain: syntax, MX, disposable and role checks first, then a made-up address to rule out a catch-all, then your address at RCPT TO, disconnecting without sending. We have not published a test of how chr-east.mx.a.cloudfilter.net answers for @bresnan.net, so we make no claim here about whether single mailboxes can be confirmed; each result carries its own reason.
Cleaning a list with these addresses
DNS tells you where mail goes, not whether one person's mailbox still exists. For a list, run the whole file through a verifier before you send: invalid rows come out, risky rows (catch-all, unknown, refused) go in their own segment, and valid rows are safe to mail.
