regular expression for ipaddress and mac address
Solution 1
import re
s = "http://[ipaddress]/SaveData/127.0.0.1/00-0C-F1-56-98-AD/"
re.search(r'([0-9A-F]{2}[:-]){5}([0-9A-F]{2})', s, re.I).group()
'00-0C-F1-56-98-AD'
re.search(r'((2[0-5]|1[0-9]|[0-9])?[0-9]\.){3}((2[0-5]|1[0-9]|[0-9])?[0-9])', s, re.I).group()
'127.0.0.1'
Place this snippet in your django routing definitions file - urls.py
url(r'^SaveData/(?P<ip>((2[0-5]|1[0-9]|[0-9])?[0-9]\.){3}((2[0-5]|1[0-9]|[0-9])?[0-9]))/(?P<mac>([0-9A-F]{2}[:-]){5}([0-9A-F]{2}))', SaveDataHandler.as_view()),
Solution 2
Your regular expression only contains two capturing groups (parentheses), so it isn't storing the entire address (the first group gets "overwritten"). Try these:
# store each octet into its own group
r"([\dA-F]{2})[-:]([\dA-F]{2})[-:]([\dA-F]{2})[-:]([\dA-F]{2})[-:]([\dA-F]{2})[-:]([\dA-F]{2})"
# store entire MAC address into a single group
r"([\dA-F]{2}(?:[-:][\dA-F]{2}){5})"
IP addresses get trickier because the ranges are binary but the representation is decimal.
# store each octet into its own group
r"(\d|[1-9]\d|1\d\d|2(?:[0-4]\d|5[0-5]))\.(\d|[1-9]\d|1\d\d|2(?:[0-4]\d|5[0-5]))\.(\d|[1-9]\d|1\d\d|2(?:[0-4]\d|5[0-5]))\.(\d|[1-9]\d|1\d\d|2(?:[0-4]\d|5[0-5]))"
# store entire IP address into a single group
r"((?:\d|[1-9]\d|1\d\d|2(?:[0-4]\d|5[0-5]))(?:\.(?:\d|[1-9]\d|1\d\d|2(?:[0-4]\d|5[0-5]))){3})"
Solution 3
You can use /^([0-2]?\d{0,2}\.){3}([0-2]?\d{0,2})$/
for IPv4 Address and /^([\da-fA-F]{1,4}:){7}([\da-fA-F]{1,4})$/i
for IPv6 address.
You can combine these two as /^((([0-2]?\d{0,2}\.){3}([0-2]?\d{0,2}))|(([\da-fA-F]{1,4}:){7}([\da-fA-F]{1,4})))$/i
. You can find a sample here.

For Mac Address You can use /^([0-9A-F]{2}[-:]){5}[0-9A-F]{2}$/i
. You can find a sample here.

can anyone suggest me the regular expression for ip address and mac address ?
i am using python & django
for example , http://[ipaddress]/SaveData/127.0.0.1/00-0C-F1-56-98-AD/
for mac address i tried following but didn't work
([0-9A-F]{2}[:-]){5}([0-9A-F]{2}) ^([0-9A-F]{2}[:-]){5}([0-9A-F]{2})$
