What was exactly the problem ?

@ryanc cool 👍

@ryanc Unless 4.2.514 is an alias name (CNAME) that represents an IP address.

@ryanc 4.2.514 is not an IPV4 address. An IPV4 address is composed of 32 bits pre-described using the dotted-interval concept, which requires a period between each group of eight (8) bits. Ex:
Format:
xxxxxxxx.xxxxxxxx.xxxxxxxx.xxxxxxxx
8 bits 8bits 8bits 8bits = 32bits
1 Byte 1 Byte 1 Byte 1 Byte = 4 Bytes
Examples of addresses:
192.168.10.4
200.29.67.4
10.10.10.2
8.8.8.8
4.4.4.4
