Code Issues Proposed changes

Temporarily remove AAAA RR for fortnebula mirror 

In the course of checking network performance in fortnebula, a
significant number of IPv6 retransmits were observed for connections
involving job nodes. While this is being looked into, fall back to
only advertising the IPv4 A RR for it in DNS so nodes will use that
exclusively when communicating with the mirror server.

This can be reverted once the cause of the retransmits is identified
and rectified.
