can't ping to internal web address

[petercinvest]

I want to know the IP address of https://ag.jp2.xyz.com/vpn/index.html, I'm currently inside company xyz 's local network, I can use web browser to open it, but i can't ping to it

[Richard Bradfield]

might have firewall setup n device to stop pings

[petercinvest]

I want to know IP address, any way?

[Mark Malone]

go to your DOS prompt on your laptop and ping the name of the website it will return an ip address ping ag.jp2.xyz.com

[petercinvest]

as mentioned by richard, ping request can't find host:ag.jp2.xyz.com

[Mark Malone]

hmm try nslookup with name of website , that's working here too when I check, if they blocked that too not sure

[petercinvest]

I use nslookup ag.jp2.xyz.com

I use nslookup https://ag.jp2.xyz.com/vpn/index.html

both said non exist domain

C:\WINDOWS>nslookup ag.jp2.xyz.com
Server:  mynetwork
Address:  192.168.2.1

Non-authoritative answer:
Name:    ag.jp2.xyz.com
Address:  52.8.203.224

This from north america.  You can't put the http:// or the url in the lookup.

[petercinvest]

no, xyz is my company name. we can't use this way, this can't work on https link, it will report as non existent domain error

this link is actually the VPN login page. any suggestion to get IP?

[pwwiddicombe]

You can't PING or NSLOOKUP to an HTTP:// header - for those you need the server (DNS) address only.

Ping ag.jp2.xyz.com will resolve to the IP address, if it exists in a DNS server (which is what you were asking in the first place).  Now, it should resolve; but quite possibly the request will time out if the server is firewalled or hardened; but should resolve the IP address. 

As the VPN login page, it's possible that it's not available internally and the reason you can https: to it is that you have a proxy server that does an external DNS lookup, but internally this isn't resolving.  The person who does the internal DNS in your company should be able to answer this.

As said, this is a DNS issue, which would explain the reason you can not connect to it in the first place.

So the appropriate records need configuring, connecting by IP is not a good idea and is a workaround, rather than a resolution!
