 ## toIPv4 {#toipv4}
 
-Like [`IPv4StringToNum`](#IPv4StringToNum) but takes a string form of IPv4 address and returns value of [IPv4](../data-types/ipv4.md) type.
+Converts a string or a UInt32 form of IPv4 address to [IPv4](../data-types/ipv4.md) type.
+Similar to [`IPv4StringToNum`](#IPv4StringToNum) and [IPv4NumToString](#IPv4NumToString) functions but it supports both string and unsigned integer data types as input arguments.
 
 **Syntax**
 
 ```sql
-toIPv4(string)
+toIPv4(x)
 ```
 
 **Arguments**
 
-- `string` — IPv4 address. [String](../data-types/string.md).
+- `x` — IPv4 address. [`String`](../data-types/string.md), [`UInt8/16/32`](../data-types/int-uint.md).
 
 **Returned value**
 
-- `string` converted to the IPv4 address. [IPv4](../data-types/ipv4.md).
+- IPv4 address. [IPv4](../data-types/ipv4.md).

 ## toIPv6 {#toipv6}
 
 Converts a string or a UInt128 form of IPv6 address to [IPv6](../data-types/ipv6.md) type. For strings, if the IPv6 address has an invalid format, returns an empty value.
-Similar to [IPv6StringToNum](#ipv6stringtonum) function, which converts IPv6 address to binary format.
+Similar to [IPv6StringToNum](#ipv6stringtonum) and [IPv6NumToString](#ipv6numtostringx) functions, which convert IPv6 address to and from binary format (i.e. `FixedString(16)`).
 
 If the input string contains a valid IPv4 address, then the IPv6 equivalent of the IPv4 address is returned.
