Hi @jluthman!

Yes, these issues are definitely related. It appears that you're using an older CentOS/RHEL version, at least I assume so given your initscripts version (reminds me of this).

In such case, if you can't update your system, you may get lucky by manually installing a newer version of ipcalc. Maybe @robert-scheck could help chiming in once again in case he knows of a better option.

Let me know how it works out.

Thanks for the feedback!

Yes, ipcalc as shipped by RHEL/CentOS 7 is simply too old. The earliest version that seems to work properly with asn is part of CentOS/RHEL/Rocky Linux 9. Replacing it is not easily possible in an update-safe way. Just replacing /usr/bin/ipcalc might be overriden with the next initscripts RPM package update, thus an alternative ipcalc would actually have to live e.g. in /usr/local/bin/ipcalc (or somewhere else on $PATH before /usr/bin to be called first). But that's nothing an RPM package from EPEL could ship, given EPEL is not allowed to replace base (CentOS/RHEL/Rocky Linux) RPM packages. So, yes, building it yourself is most likely the way to go. If it helps somehow, I could ship a "bad" RPM package within a Fedora COPR repository (outside of the regular distribution) to provide what's needed for asn…let me know, if there is interest.

Robert's solution/repo is perfect. Simply run the dnf commands and it works.

ipcalc -v

ipcalc 1.0.1

which ipcalc

/usr/local/bin/ipcalc
