Inserts or deletes
IPSetDescriptor objects in an
IPSet
. For each
IPSetDescriptor
object, you specify the following values:
-
Whether to insert or delete the object from the array. If you want to change an IPSetDescriptor
object, you delete the existing object and add a new one.
-
The IP address version, IPv4
or IPv6
.
-
The IP address in CIDR notation, for example, 192.0.2.0/24
(for the range of IP addresses from 192.0.2.0
to 192.0.2.255
) or 192.0.2.44/32
(for the individual IP address 192.0.2.44
).
AWS WAF supports /8, /16, /24, and /32 IP address ranges for IPv4, and /24, /32, /48, /56, /64 and /128 for IPv6. For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing.
IPv6 addresses can be represented using any of the following formats:
You use an IPSet
to specify which web requests you want to allow or block based on the IP addresses that the requests originated from. For example, if you're receiving a lot of requests from one or a small number of IP addresses and you want to block the requests, you can create an IPSet
that specifies those IP addresses, and then configure AWS WAF to block the requests.
To create and configure an IPSet
, perform the following steps:
-
Submit a CreateIPSet request.
-
Use GetChangeToken to get the change token that you provide in the ChangeToken
parameter of an UpdateIPSet request.
-
Submit an UpdateIPSet
request to specify the IP addresses that you want AWS WAF to watch for.
When you update an IPSet
, you specify the IP addresses that you want to add and/or the IP addresses that you want to delete. If you want to change an IP address, you delete the existing IP address and add the new one.
