eircom.net MX records
eircom.net publishes 2 MX hosts, all at priority 20, so senders spread mail across them.
5 other domains we checked on the same day also route mail to hosts under cloudfilter.net, with different records from eircom.net: brighthouse.com, mchsi.com, mediacombb.net, bresnan.net and midco.net.
eircom.net SPF record
The record on 5 November 2026 was v=spf1 include:eir.spf.a.cloudfilter.net ip4:159.134.118.0/24 ip4:213.94.190.10/27 ip4:86.43.60.0/24 ip4:86.43.56.163/28 ip4:83.70.171.121/32 ip4:159.134.245.1 ip4:159.134.245.129 mx ~all.
In plain terms, it delegates to eir.spf.a.cloudfilter.net and lists 7 IP ranges directly. The top level uses 2 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.
eircom.net DMARC policy
The record is v=DMARC1; p=none; pct=100; fo=1; ri=3600; rua=mailto:[email protected],mailto:[email protected]; ruf=mailto:[email protected];.
p=none only asks for reports; failing mail is delivered as normal.
Aggregate reports go to inbox.ondmarc.com and eircom.net, so the domain's owner sees who sends mail as @eircom.net.
Can you verify @eircom.net addresses?
Our checker treats @eircom.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 eir-07.mx.a.cloudfilter.net answers for @eircom.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.
