Good question. Making a device change its DNS name won't work in most
cases (unless you assume that the device is able to make dynamic DNS
updates and the server is willing to accept them). Also, returning the
DNS name would in prinicple mean that you have to do a DNS lookup every
time you return the value since the DNS name might change without
notifying the device. Note sure this would be practical or useful.
In fact, most implementations probably just use sysName to store a
locally significant name and leave it to the administrator to sync.
that with the DNS name.
Bottom line: There seems to be a conflict here with the content of
the description clause and current usage / implementation. Would be
nice to know what commercial implementations do with this object.
