# Quotas and limits in Network Load Balancer

Yandex Network Load Balancer has the following limits:

* [_Quotas_](https://console.yandex.cloud/cloud?section=quotas) are organizational constraints that can be changed by contacting technical support.
* _Limits_ are technical constraints of the Yandex Cloud architecture. You cannot change the limits.

If you need more resources, you can increase your quotas in one of the following ways:

* [Make a request to increase your quotas](https://console.yandex.cloud/cloud?section=quotas).
* Contact [support](https://center.yandex.cloud/support) and specify which quotas you want increased and by how much.

To have your request processed, you must have the `quota-manager.requestOperator` [role](../../iam/roles-reference.md#quota-manager-requestoperator) or higher, e.g., `editor` or `admin`.

You can manage your quotas with [Cloud Quota Manager](../../quota-manager/quickstart.md).

#### Quotas {#load-balancer-quotas}

#|
|| Type of limitation | Value ||
|| Number of load balancers per cloud
`ylb.networkLoadBalancers.count` | 2 ||
|| Number of target groups per cloud
`ylb.targetGroups.count` | 100 ||
|#

#### Limits {#load-balancer-limits}
Type of limitation | Value
----- | -----
Number of targets per target group | 254
Number of ports per listener | 10
Number of health checks per attached target group | 1
Health check protocol | TCP, HTTP

#### Other restrictions {#load-balancer-other-restrictions}
A single target group can only contain targets from a single cloud network. 

Within a single availability zone, a target group can only include targets on the same subnet.

If you add a target to the internal load balancer's target group, it will not be directly accessible on the target port.

You can create a load balancer without a listener.

Health check traffic comes from the `198.18.235.0/24` and `198.18.248.0/24` ranges.

When adding targets for a load balancer, keep in mind the [limit](../../vpc/concepts/limits.md#limits) on the maximum number of concurrent TCP/UDP connections per VM.
