If someone uses Nettica.com (to manage DNS records), is there any chance, how to find out hosting provider?

Example

http://who.is/dns/evernote.com/

evernote.com NS 1 day  dns5.nettica.com
evernote.com NS 1 day  dns1.nettica.com
evernote.com NS 1 day  dns2.nettica.com
evernote.com NS 1 day  dns3.nettica.com
evernote.com NS 1 day  dns4.nettica.com

Questions

  • Which hosting provider does Evernote use?
  • Why Evernote use Nettica.com? What's the advantage?

Thank you.

The DNS and webserver hosting can be totally independent. As is in this case.

Your best bet is:

  • Check the DNS records:

    host evernote.com
    

    should give you something like this:

    evernote.com has address 205.234.25.136
    evernote.com mail is handled by 30 aspmx5.googlemail.com.
    [...]
    

    We know that web hosting is done at 205.234.25.136, and e-mail gets handled by Google (Apps for Your Domain).

  • Try checking the obtained IP in RIPE database: Query RIPE Database

    Here it's a nondescript IANA-BLK, so we don't know much.

  • In that case we can try a traceroute to the web host:

    traceroute evernote.com
    [...]
    18  border3.pc1-bbnet1.sje.pnap.net (66.151.144.9)
    19  qts-28.border3.sje.pnap.net (70.42.255.234)
    20  205.234.0.42 (205.234.0.42)
    21  www.evernote.com (205.234.25.136)
    

    Looking at this we can make a guess that evernote is using www.internap.com

    Correction: As pointed out - ARIN database is more accurate in this case:

    http://ws.arin.net/whois/?queryinput=205.234.25.136

Now when I look at pQd answer - it's probably more precise. Internap could be an intermediary provider of some sort. – Karol Piczak Apr 21 '10 at 15:10

check to what ip does evernote.com point:

pqd:~$ dig +short evernote.com
205.234.25.136

[ or just http://www.robtex.com/dns/evernote.com.html ]

and 205.234.25.136 belongs to Quality Technology Services Santa Clara.
