Syntax
ping [-t] [-a] [-n number] [-l bytes] [-f] [-i TTL] [-v TOS] [-r number]
[-s hops] [ [-j hostlist] | [-k hostlist] ] [-w msec] host [...]
Options
- -t
Continues pinging the host until interrupted using Ctrl-C.- -a
Resolves IP addresses to hostnames.- -n number
Specifies the number of ICMP ECHO packets to send. (The default is
four packets.)- -l bytes
Indicates number of bytes in each ECHO packet. (The default is 32
bytes, and the maximum is 65,527 bytes.)- -f
Sets the Do Not Fragment flag in the packets to prevent them from
being fragmented by routers along the route.- -i TTL
Sets the time-to-live field in the packets.- -v TOS
Sets the Type of Service field in the packets.- -r number
Records the route of the outgoing packet and the returning packet in
the Record Route field. (The minimum number of hosts you can specify
is one, and the maximum is nine.)- -s hops
Specifies the timestamp for the number of hops specified by number.- -j hostlist
Routes packets using the specified list of remote hosts (up to nine).
Consecutive hosts can be separated by intermediate gateways (loose
source routing).- -k hostlist
Routes packets using the specified list of remote hosts (up to nine).
Consecutive hosts can't be separated by intermediate
gateways (loose source routing).- -w msec
Specifies timeout interval in milliseconds.- host
Indicates IP address or hostname of remote host(s) being

Examples
ping a remote host:
ping www.gov.mb.ca
Pinging www.gov.mb.ca [198.163.12.46] with 32 bytes of data:
Reply from 198.163.12.46: bytes=32 time=140ms TTL=250

Notes
- By default, ping sequentially sends four 32-byte
ICMP ECHO packets to the remote host and waits one second for a
reply. - If you can ping the remote host by IP address but not by hostname,
there is probably a DNS problem.
