ping the localhost network.

it's not the nameserver. It's the domain "cyberia.net.sa" that has
"localhost" in it pointing go 127.0.0.1

This is useless. The localhost hostname should not exist in domains other
than "localhost." that should be configured on recursive servers.

Any suggestions would be appreciated

simply remove the "localhost" record from cyberia.net.sa and possibly other domains.

Hrmmm... I'm reminded of something else I've seen reported on recently...

I don't know if you've been paying attention, but it's been reported that among others EBay has been port scanning visitor's devices [0]. Having localhost.ebay.com could be handy for them in terms of circumventing some rules on setting of cookies and the execution of scripts. Not saying
that's what they're doing, heaven forbid.

Any domain you visit could have entries in it which point to e.g.
localhost or nonrouting addresses commonly used for gateways, things like that.

This is not a DNS problem, it's a problem in what commonly used programs
aid and abet in the name of "freedom of commerce" or something.

It's possible to block with rpz & something else that I can't recall
right now. I did RPZ blocking first, so I didn't bother changing

; return NXDOMAIN for any 127.0.0.0/8 answers
; exceptions:
onea.net-snmp.org CNAME rpz-passthru.
twoa.net-snmp.org CNAME rpz-passthru.
localhost CNAME rpz-passthru.
8.0.0.0.127.rpz-ip CNAME . ; 127.0.0.0/8
; check:
; localhost 127.0.0.1
; onea.net-snmp.org 127.0.0.1
; twoa.net-snmp.org 127.0.0.2 127.0.0.3

All my other host names that used to return 127.0.0.1 answers don't
any more :( Anyone know some valid names I can use for testing?
