I previously had a domain hosted on a dedicated server at the local university. We moved the hosting to a dedicated dreamhost server. In Dreamhost, I set up ums.org to be fully hosted by Dreamhost. Here are my settings:
Record (ums.org zone) Type Value A 126.96.36.199 NS ns1.dreamhost.com. NS ns2.dreamhost.com. NS ns3.dreamhost.com. ftp A 188.8.131.52 ssh A 184.108.40.206 www A 220.127.116.11
About 24 hours ago, I asked the local university to switch their nameservers to dreamhosts nameservers for our domain, so they were previously dns.itd.umich.edu and dns2.itd.umich.edu, I needed them switched to ns1.dreamhost.com, ns2.dreamhost.com, and ns3.dreamhost.com.
The old server was 18.104.22.168, the new server is 22.214.171.124.
When I do an 'nslookup -q=any ums.org', I get the following (I'm a developer, so I'm not entirely sure how to decipher this):
Non-authoritative answer: ums.org text = "v=spf1 a mx include:wordfly.com ~all" ums.org RP mailbox = johnp.umich.edu.ums.org text location = (root) ums.org internet address = 126.96.36.199 ums.org nameserver = ns1.dreamhost.com ums.org nameserver = ns2.dreamhost.com ums.org nameserver = ns3.dreamhost.com ums.org primary name server = dns.itd.umich.edu responsible mail addr = hostmaster.umich.edu serial = 201208023 refresh = 1800 (30 mins) retry = 900 (15 mins) expire = 2419200 (28 days) default TTL = 1800 (30 mins) ums.org MX preference = 0, mail exchanger = logo.web.itd.umich.edu ns2.dreamhost.com internet address = 188.8.131.52 ns3.dreamhost.com internet address = 184.108.40.206 ns1.dreamhost.com internet address = 220.127.116.11
Since my primary name server is still dns.itd.umich.edu, is that something that needs to be changed?
When I look at 'A' records here: http://www.whatsmydns.net/#A/ums.org , it appears that it's about 50% propagated. However, it seems like some of these servers are switching back and forth (I checked yesterday, too).
When I look at 'NS' records here: http://www.whatsmydns.net/#NS/ums.org , it seems like my NS records were changed properly.
HOWEVER, when I go to http://whois.domaintools.com/ums.org or http://www.dnsstuff.com/tools#whois/type=domain&&value=ums.org&& , it still uses my old nameservers.
Which site can I trust? How can I tell if this is working? How long does this normally take? Are there any additional steps I need to take besides changing the nameservers?
