DNS connectivity checking: The query

## 3. The query

Linuxconf sends the following query to the DNS

> `

>             nslookup -q=soa 0.0.127.in-addr.arpa

> `

It is believed that all properly configured DNS should answer this request. It is possible that a working DNS operates without a reverse mapping for the network 127.0.0. This is a flaw and should be corrected. (Run linuxconf on this machine and configure the DNS with it and linuxconf will silently fix this.)
