The available netsh http commands are:

add iplisten

Adds a new IP address to the IP listen list, excluding the port number.

Syntax

add iplisten [ ipaddress= ] IPAddress

ipaddress The IPv4 or IPv6 address to be added to the IP listen list. The IP listen list is used to scope the list of addresses to which the HTTP service binds. "0.0.0.0" means any IPv4 address and "::" means any IPv6 address. Required

Examples

Following are four examples of the add iplisten command.

  • add iplisten ipaddress=fe80::1
  • add iplisten ipaddress=1.1.1.1
  • add iplisten ipaddress=0.0.0.0
  • add iplisten ipaddress=::

add sslcert

Adds a new SSL server certificate binding and corresponding client certificate policies for an IP address and port.

Syntax

add sslcert [ ipport= ] IPAddress:port [ certhash= ] CertHash [ appid= ] GUID [ [ certstorename= ] CertStoreName [ verifyclientcertrevocation= ] enable | disable [verifyrevocationwithcachedclientcertonly= ] enable | disable [ usagecheck= ] enable | disable [ revocationfreshnesstime= ] U-Int [ urlretrievaltimeout= ] U-Int [sslctlidentifier= ] SSLCTIdentifier [ sslctlstorename= ] SLCtStoreName [ dsmapperusage= ] enable | disable [ clientcertnegotiation= ] enable | disable ] ]

Parameters

ipport Specifies the IP address and port for the binding. A colon character (:) is used as a delimiter between the IP address and the port number. Required
certhash Specifies the SHA hash of the certificate. This hash is 20 bytes long and is specified as a hexadecimal string. Required
appid Specifies the GUID to identify the owning application. Required
certstorename Specifies the store name for the certificate. Defaults to MY. Certificate must be stored in the local machine context. Optional

revocationfreshnesstime Specifies the time interval, in seconds, to check for an updated certificate revocation list (CRL). If this value is zero, then the new CRL is updated only if the previous one expires. Optional
urlretrievaltimeout Specifies the timeout interval (in milliseconds) after the attempt to retrieve the certificate revocation list for the remote URL. Optional
sslctlidentifier Specifies the list of the certificate issuers that can be trusted. This list can be a subset of the certificate issuers that are trusted by the computer. Optional
sslctlstorename Specifies the certificate store name under LOCAL_MACHINE where SslCtlIdentifier is stored. Optional
