How not to set up your DNS (part 3)

Presented once again in illustration:

; sdig ns isotech.com.cy
dns2.lordosinfo.com.
dns1.lordosinfo.com.
; sdig ns lordosinfo.com.
dns1.edynet.com.cy.
dns1.lordosinfo.com.
; sdig ns edynet.com.cy.
dns2.netconnect.com.cy.
dns1.netconnect.com.cy.

At the moment:

• dns2.netconnect.com.cy is not responding,
• dns1.edynet.com.cy doesn't exist according to dns1.netconnect.com.cy,
• dns2.lordosinfo.com is a CNAME to outopos.lordosinfo.com,
• and outopos.lordosinfo.com is a CNAME to itself (that's good for bonus points).

In the face of all of this, our DNS server is currently laughing hysterically at the very idea of looking up A and MX records for isotech.com.cy. (In fact it bitches about 'protocol error', possibly due to the nice CNAME loop.)
