w> IP addresses are likely to be all on the same subnet
| Adv: ZoneCheck
| To avoid loosing all connectivity with the authoritative DNS in case
| of network outage it is advised to host the DNS on different networks.
|
| Ref: IETF RFC2182 (Abstract)
| The Domain Name System requires that multiple servers exist for every
| delegated domain (zone). This document discusses the selection of
| secondary servers for DNS zones. Both the physical and topological
| location of each server are material considerations when selecting
| secondary servers. The number of servers appropriate for a zone is also
| discussed, and some general secondary server maintenance issues
| considered.

: All the servers are likely to be on the subnet 85.24.156.0/28, try
: moving some of them to another subnet.

w> Nameservers are all part of the same AS
| Adv: ZoneCheck
| To avoid loosing all connectivity with the authoritative DNS in case
| of a routing problem inside your Autonomous System, it is advised to
| host the DNS on different AS.

| Adv: default registry policy
| The registry requieres the SOA fields to be inside a defined range:
| the 'expire' should be between 1W and 6W, the 'minimum' between 3M and
| 1W, the 'refresh' between 1H and 2D, and at last the 'retry' between
