Converts IPv6 or IPv4 string to a canonical IPv6 string representation.

parse_ipv6("127.0.0.1") == '0000:0000:0000:0000:0000:ffff:7f00:0001'
parse_ipv6(":fe80::85d:e82c:9446:7994") == 'fe80:0000:0000:0000:085d:e82c:9446:7994'

Syntax

parse_ipv6(Expr)

Arguments

  • Expr: String expression representing IPv6/IPv4 network address that will be converted to canonical IPv6 representation. String may include net-mask using IP-prefix notation.

IP-prefix notation

IP addresses can be defined with IP-prefix notation using a slash (/) character. The IP address to the LEFT of the slash (/) is the base IP address. The number (1 to 127) to the RIGHT of the slash (/) is the number of contiguous 1 bits in the netmask.

Returns

If conversion is successful, the result will be a string representing a canonical IPv6 network address. If conversion isn't successful, the result will be null.

Example

datatable(ipv4:string)
[
 '192.168.255.255',
 '192.168.255.255/24',
 '255.255.255.255'
]
| extend ipv6 = parse_ipv6(ip_string)
ipv4 ipv6
