Michael: To determine why there is no DNSSEC information being returned by your 
dig query, consider the following:

What are the timestamps in your key metadata? Are they currently published and 
active?
nstest/etc/namedb/keys;dnssec-settime -p all 
Ktransnetworks.net.+005+54607.private

What are the file modes and ownership of your keys? Can named running under 
whatever UID it is using read the keys?

What are the full contents of your unsigned and signed zone files? Any clues 
there?
nstest/etc/namedb/keys;named-checkzone -j -o - transnetworks.net 
transnetworks.net
nstest/etc/namedb/keys;named-checkzone -j -f raw -o - transnetworks.net 
transnetworks.net.signed

Are there syslog messages that indicate any problems signing your zone?
nstest/etc/namedb/keys;cat /var/log/syslog | grep named

Ultimately with dnssec-dsfromkey, you may wish to leave out "-2" and generate 
both SHA-1 and SHA-256 digests. Depending on your registrar, they may accept 
one, the other, or both. The DS record submission is usually done on your 
registrar's web site.

With dnssec-keygen, I used "-b 2048". I don't think there is a compelling 
argument for using a shorter key.

Note that dig +dnssec queries targeted at your authoritative server will 
ultimately return DNSSEC records but will never return an AD flag. Eventually 
you will want to see the AD flag to know that all is well with the chain of 
trust though "net." up to the DNS root zone, and for this you will need a 
DNSSEC-enabled recursive resolver. You can use DNS-OARC's open validating 
resolver to test: https://www.dns-oarc.net/oarc/services/odvr. You can fairly 
easily set up another bind server as a recursive resolver for your own use as 
well. Two other good tests for your DNSSEC-enabled zones are at 
http://dnsviz.net/ and http://dnssec-debugger.verisignlabs.com/.
