Screenshot 150- DNS Lookup - setup Window
To obtain information about a domain name:
1. Go to the Tools > ‘DNS lookup’ node.
2. Specify the hostname to resolve.
3. Specify the information to be retrieved.
• Basic Information – i.e. host name and what IP this resolves.
• Host Information - known technically as the HINFO, usually
includes information such as hardware and what OS runs on the
specified domain (most DNS entries do not contain this information
for security reasons).
• Aliases - return information on any A Records the Domain might
have.
• MX Records - known also as Mail exchangers records, show
which mail server(s) in order, are responsible for this domain.
• NS Records - indicate which name servers are responsible for this
domain.
In addition it is possible to specify alternative DNS servers.
Whois
This tool looks up information on a domain or IP address. You can
select a specific Whois Server from the options area, or you can use
the 'Default' option which will select a server for you.
