Hi,

I like to ask if i have an existing NS1 nameserver that points to for example 88.88.88.88
and i just changed the IP now to 99.99.99.99

How do i check when the change take effect (propagate) such that when i nslookup the NS1
nameserver it will show 99.99.99.99.

Thanks!

You can use dig:

$ dig @resolver ns1.yourdomain.com

where resolver is dns servers of various ISPs.  You can test with the list of resolvers here:

resolver.qwest.net
vnsc-lc.sys.gtei.net
ns-1.iastate.edu
dns1.mci.com
ns1.us.prserv.net
ns2.mindspring.com
dns1.rcsntx.sbcglobal.net
ns2.us.dellhost.com
ns3.earthlink.net
ns.isi.edu
ns1.super-dns.com
ns1.sprintlink.net
cache01.ns.uu.net
ns1.mcleodusa.net
gizmo55bw.bigpond.com
dnscache1.singnet.com.sg
dns1.cableplus.com.cn
ns1.interplanet.com.mx


Or you can use nslookup:

$ nslookup
> server resolver
> yourdomain.com
> exit

Could you post the response here?  Mask your real domain name and IP if you are worry about security.  Normal response should have something like:

;; ANSWER SECTION:
ns1.yourdomain.com.         86400   IN      A       99.99.99.99

Without even knowing it, most of us are using web applications on a daily basis. Gmail and Yahoo email, Twitter, Facebook, and eBay are used by most of us daily—and they are web applications. We often confuse these web applications tools for websites.  So, what is the difference?

this replies show that your ns1.*. 's IP is currently pointing to 19*.  3939 is the refresh time if I am not wrong, so is 172800.
