I want to validate an IP address and found this. Import doesn't seem to work so I tried just copy the code into Project Library [https://github.com/python/cpython/blob/3.11/Lib/ipaddress.py](https://github.com/python/cpython/blob/3.11/Lib/ipaddress.py) but that doesn't seem to work either.

I'm guessing it is because this is 3.3 and ignition runs 2.7 python version.

Is there something that works in 2.7?

main function I am looking for is something that takes a string and verifies it is a valid IP address IPV4.

Generally, you'd pass whatever you have to `java.net.InetAddress.getByName()`, and then check if you got an instance of `Inet4Address`. As a side benefit, it will look up a provided hostname, too.

```auto
import java
ipaddress = "162.2.2.999"

try:
	java.net.InetAddress.getByName(ipaddress)
except:	
	print "no good"
else: 
	print "good"

```

looks like that works. Thanks.

Holy Moly, don't do that. You're importing all of the java "name space".

Like this:

```auto
from java.net import InetAddress
ipaddress = '162.2.2.999'
try:
   InetAddress.getByName(ipaddress)
   print 'good'
except:
   print 'no good'

```

Uhm, you said you wanted to check for an IPv4 address. The above will allow IPv6 addresses. Use this:

```auto
from java.net import InetAddress, Inet4Address
ipaddress = '162.2.2.999'
try:
   addr = InetAddress.getByName(ipaddress)
   if isinstance(addr, Inet4Address):
      print 'good'
   else:
      print 'not IPv4'
except:
   print 'no good'

```
