Figure 2-13 Tracert utility example.
The following things can be noted about this traceroute:
• The traceroute lists the IP address for the host (213.48.95.8).
• The first router hop displayed is the default gateway of the host from which the
traceroute was executed. It is on a private network (10.10.8.1).
• The second hop is the router port on the external network (209.3.205.180).
• The remaining hops trace the route across the internet to the host.
• Connectivity to this host was reached in an acceptable time frame (130
milliseconds).
nslookup The nslookup (name server look up) command is an application that queries a DNS
database for information about its DNS entries. This is useful if you suspect domain
resolution or DNS configuration problems on a host. You can query any DNS server
(if you know its name or IP address) but, by default, queries are run against the DNS
server configured for the host requesting the lookup.
Typical use of the
nslookup command for a Windows-based host is:
nslookup <ipaddress> <server>
or
nslookup <domainname> <server>
where
<ipaddress> is the IP address of a host you want information about.
<domainname> is the name of the host domain you want information about.
<server> is the name or IP address of a server other than the default. This parameter
is optional.
