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

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.
