+.SH DESCRIPTION
+.BR ether_aton ()
+converts the 48-bit Ethernet host address
+.I asc
+from the standard hex-digits-and-colons notation into binary data in
+network byte order and returns a pointer to it in a statically
+allocated buffer, which subsequent calls will
+overwrite.
+.BR ether_aton ()
+returns NULL if the address is invalid.
+.PP
+The
+.BR ether_ntoa ()
+function converts the Ethernet host address
+.I addr
+given in network byte order to a string in standard
+hex-digits-and-colons notation, omitting leading zeros.
+The string is returned in a statically allocated buffer,
+which subsequent calls will overwrite.
+.PP
+The
+.BR ether_ntohost ()
+function maps an Ethernet address to the
+corresponding hostname in
+.I /etc/ethers
+and returns nonzero if it cannot be found.
+.PP
+The
+.BR ether_hostton ()
+function maps a hostname to the
+corresponding Ethernet address in
+.I /etc/ethers
+and returns nonzero if it cannot be found.
+.PP
+The
+.BR ether_line ()
+function parses a line in
+.I /etc/ethers
+format (ethernet address followed by whitespace followed by
+hostname; \[aq]#\[aq] introduces a comment) and returns an address
+and hostname pair, or nonzero if it cannot be parsed.
+The buffer pointed to by
+.I hostname
+must be sufficiently long, for example, have the same length as
+.IR line .
+.PP
+The functions
+.BR ether_ntoa_r ()
+and
+.BR ether_aton_r ()
+are reentrant
+thread-safe versions of
+.BR ether_ntoa ()
+and
+.BR ether_aton ()
+respectively, and do not use static buffers.
+.PP
+The structure
+.I ether_addr
+is defined in
+.I <net/ethernet.h>
+as:
+.PP
+.in +4n
+.EX
+struct ether_addr {
+    uint8_t ether_addr_octet[6];
+}

+In glibc 2.2.5 and earlier, the implementation of

+.\" The fix was presumably commit c0a0f9a32c8baa6ab93d00eb42d92c02e9e146d7
+.\" which was in glibc 2.3
+is broken.
