Assuming the following dns zone configuration for kresin.me:
. 1800 IN NS ns.inwx.de.
home.kresin.me. 1800 IN NS gw.home.kresin.me.
gw.home.kresin.me. 60 IN A 198.51.100.1
Using the example, gw.home.kresin.me is a glue record and used as DDNS
record as well. gw.home.kresin.me points to the OpenWrt installation
where the ddns-scripts are running.
Since ns.inwx.de isn't the authoritative server for home.kresin.me,
a query for the the A record of gw.home.kresin.me will be "forwarded"
to and replied by the authoritative server 198.51.100.1. If the
authoritative server can't be reached, the query times out without any
address returned.
The only way to get the A record of the glue record is to use bind
host in verbose output mode, query ns.inwx.de for gw.home.kresin.me and
evaluate the additional section of the response.
To my knowledge, only bind host in verbose output mode shows the
additional section of the response. Therefore, this features depends on
bind host.
It is not possible to use the bind host verbose mode for all queries.
In verbose mode the "has address" line isn't returned. Grepping for the
hostname might fail if the hostname is CNAME. Grepping for the first
occurrence of an ip-address is way to error prone, since it could
return the ip address of a different record type.
