Your first group is matching From:
<sip:anonymous@[2008:abcd:1234:2260:208:5dff:fe93:5b6
but it looks like you want it to only match <sip:anonymous@. Try escaping
the brackets, the regex engine is interpreting them as a list instead of
matching the literal "[]" characters.
subst('/^From:(.*)\[2008:abcd:1234:2260:208:5dff:fe93:5b65\](
.*)>(.*)/From:\1[2008:abcd:1234:2260:20c:29ff:fe9a:b9cb]>\3/ig');

Thanks John for the Reply.
So if i understand properly :
group 1 is here <sip:anonymous@
group 2 is empty
group 3 is ;tag=41008079_nab_FFFF_isp_FFFF_cco_FFFF_igo_FFFF_mgt_78DD
the previous expression is working for IPv4.
Now for IPv6
Input : From: <sip:anonymous@[2008:abcd:
1234:2260:208:5dff:fe93:5b65]>;tag=42006C96_nab_FFFF_isp_
FFFF_cco_FFFF_igo_FFFF_mgt_8092
subst('/^From:(.*)[2008:abcd:1234:2260:208:5dff:fe93:5b65](
.*)>(.*)/From:\1[2008:abcd:1234:2260:20c:29ff:fe9a:b9cb]>\3/ig');
Output : From: <sip:anonymous@[2008:abcd:
1234:2260:208:5dff:fe93:5b6[2008:abcd:1234:2260:20c:29ff:
fe9a:b9cb]>;tag=42006C96_nab_FFFF_isp_FFFF_cco_FFFF_igo_FFFF_mgt_8092
//what is going wrong here?
Here
group 1 is <sip:anonymous@
group 2 is empty
group 3 is ;tag=42006C96_nab_FFFF_isp_FFFF_cco_FFFF_igo_FFFF_mgt_8092
what mistake am i making for IPv6 ? if you see the output.
Regards,

They are references to groups in the regex match.
The groups are in
parenthesis. Whatever is matched by group 1 and 3 will be included in the
substitution.
https://regexr.com/ and https://regex101.com/ are both good sites for
building and explaining regexes.
