# Validin CIDR Calculators

### Individual IP/CIDR Calculators

#### Range to CIDRs

Given first and last IP, convert to CIDRs

#### IP/CIDR fencepost IPs

Find IPs and CIDRs at the beginning/end ranges of given

#### CIDR Siblings

Find previous and next CIDRs that are the same size as the given CIDR

### Set Calculators

#### Simplify

Find the minimal CIDR representation for a set of IPs and CIDRs

#### Inverse

Return the inverse of the given set of CIDRs

#### Decompose

Break a CIDR or CIDRs into CIDRs no larger than N prefix bits

#### Relative Complement

Subtract the CIDRs in B from the CIDRs in A. If part of a CIDR in A overlaps with B, return the nonoverlapping part.

#### Overlap

Find the CIDRs in A that include any CIDRs from B.
