Nowhere even close to ridiculously large.  3600000 (10000 hours, 41
days) is the historical example value in RFC 1035.  It's a bit larger
than current recommended practices (2-4 weeks) but I wouldn't fault
anyone for using that value nor would I expect any nameserver software
to malfunction when confronted it.  Besides, that value only matters
to secondary nameservers.  Speaking of that...

ns1.nineplanetshosting.com. 172800 IN   A
ns2.nineplanetshosting.com. 172800 IN   A

I think OP ought to approach his hoster with a cluebat.  Not just on
the same subnet but the same address?  Really.
