I'm seeing 10s TTL on records defined withing local DNS server

nslookup -debug=on zyxel.e.com 192.168.1.1

Got answer:
HEADER:
opcode = QUERY, id = 5, rcode = NOERROR
header flags: response, auth. answer, want recursion, recursion avail.
questions = 1, answers = 0, authority records = 1, additional = 0

QUESTIONS:
zyxel.e.com, type = AAAA, class = IN
AUTHORITY RECORDS:
->e.com
ttl = 10 (10 secs)
primary name server = localhost
responsible mail addr = root.localhost
serial = 2008122601
refresh = 28800 (8 hours)
retry = 14400 (4 hours)
expire = 604800 (7 days)
default TTL = 86400 (1 day)

Although this doesn't do DNS resolvers much justice, this is probably intentional to put the router's memory to better use, or to keep the router more stable in the event of high buffer use or a DNS Exploit.
